The question has recently arisen, "Is Obama a Muslim?" It's a fair and valid question. Knowing someone's religious beliefs -- true religious beliefs -- tells you something about that person.
In Matthew 7:16 we see these words, "You shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?" We see it elsewhere in the Bible as, "As the old saying goes, 'From evildoers come evil deeds,' so my hand will not touch you." (1 Samuel 24:13), or "My brothers, can a fig tree bear olives, or a grapevine bear figs? Neither can a salt spring produce fresh water." (James 3:12), and, "Even a child is known by his actions, by whether his conduct is pure and right." (Proverbs 20:11).
Say, for instance, your brother just announced he has recently become a Catholic. You believe he is sincere in his statement because he has been honest with you in every instance of conversation and written communication previously, so you believe his conversion to Catholicism to be genuine. You now know that he has accepted as important and -- hopefully -- factual, the teachings of the Catholic Church. That tells you that he will now be doing some predictable things: using a rosary, praying certain prayers, going to certain church services, eating certain things (or not eating them), etc. You know that he is now going to be crossing himself, wearing a Crucifix instead of an empty cross; he'll be praying to Saints and Martyrs instead of just God via Jesus Christ. You know what to expect. You're familiar with the signs and "symptoms" of being a Catholic. If your brother does not do those things, then you can seriously doubt his conversion statement as being legitimate and sincere.
Same holds true of Obama being a Christian. Obama says he is a Christian. Therefore, according to the Bible, we should see certain things from him as far as his actions and words are concerned. We should see him going to a church that teaches and preaches the Bible as the loving word of God. Instead, he spent twenty years as a member and regular attendee of the "Rev." Jeremiah Wright's, "Not God Bless America, but God d**n America!" and "America's chickens are coming home to roost!" Sitting under tutelage like that for twenty years, having the "Rev." Wright perform your marriage ceremony and baptise your daughters: Christian fruit, or hatred?
Considering that he has left Chicago and is now in the Red House (used to be the White House until a Marxist/Communist occupied it), his church going has changed. He no longer regularly attends any church. In fact, in his first year in office, he attended church only three times. So church attendance is not something that labels him a Christian. Of course, there is no truth to the fact that everyone who attends church is a Christian, nor that anyone who does not attend church is not a Christian. So with that, I will cut him some leeway. However, I must make two observations on the story linked above. 1) We are told that Obama "prays every day." So do Muslims, some Atheists, Druids, Hindus, Buddhists, etc. "[P]ray[ing] every day" proves nothing toward or against Christianity. 2) Obama supposedly gets his daily Christian lessons on his Blackberry (instead of from his Bible, but okay), but that does not mean that he reads them. Ever hear him spontaneously and accurately quote an appropriate Bible verse? Spontaneously, now, not in a scripted speech? No? Nor have I.
Let's look at some other indicators. In Malachi 3:10 we see that we are supposed to bring our tithes "into the storehouse" in obedience to God to further His kingdom. Leviticus 27:30 says for us to tithe of "everything from the land" and we are taught that one tenth of every bit of our income is supposed to go to God -- before deductions and "adjusted income" is figured. We're supposed to tithe our gross income. According to Obama's charitable donations, we see only $250 went to a church or Christian foundation/organization. The rest of his donations -- even the money from his Pulitzer Prize -- went to other kinds of non-Christian organizations. Is that being obedient to God's word? Is that how he demonstrates with the fruit he bears how much he loves the God of the Bible?
Another consideration is the story he tells of his conversion experience. What does he say about that first moment when God knocked on Obama's heart and called Obama to be His son? Where was he? How did it feel? Who else was there? What did God say? Who did Obama tell first? What happened next inside Obama's heart? How did Obama's heart change? How did Obama's actions change? What was Obama's first desire regarding Obama's service to God? How was Obama's life made different? Has anyone ever heard it and did it sound anything at all like the truth? It is in one of his books that "he wrote of it" (I put that in quotes because I am not sure it was he who wrote those books, there is evidence he did not). If it be someone else's words, then this testimony is not necessarily Obama's testimony and considering that it is not elsewhere mentioned within the book, in fact quickly forgotten, and not in evidence today, I think that the fruit of that testimony is lacking in freshness. Many have a "conversion" that lasts but a moment and no more. Many go forward in church and some even go so far as to be baptized (sometimes even to prove something to a girl within the church, or similar non-Christian motives), but unless that conversion experience changes your heart and life so that you are truly different -- and we've seen no evidence of that -- then it is not a conversion, but a show.
Does someone professing Christianity respect the Bible, quote it correctly, and follow its precepts? Or does he quote the Koran and claim it's part of the Bible, and mock the Bible? If the latter, then I would definitely say it's okay to doubt one's supposed Christianity because that person is mocking God. A true Christian does not mock God because a true Christian would be horrified at the idea of doing so, and would be too scared of the consequences. Someone who says they are a Christian would know better than to mock God. The fruit of that tree is total annhiliation via God's wrath, not the growth of God's kingdom. If the good fruit comes from the good tree, then the tree Obama is planting is a tree of death.
Questioning Obama's Christianity is legitimate because of the fact that he is hateful toward Christianity as a whole. Remember his quote, "it's not surprising that they cling to guns or religion"? Sorry, but a Christian would say that? Would a Christian say that it isn't surprising that people would be Christians? He said that it isn't "surprising that they cling to guns or religion". A Christian would down being a Christian? Is that the fruit of a good tree, or is that a thorn from a thorn tree?
Something else to take into consideration as a "fruit" is, if he is a Christian, does he preach what he supposedly practices? Does he tell others that it's good to be a Christian? Does he follow the Great Commission in Matthew 28:16-20 -- is Obama a witness for Christ? Or does Obama say he is still a Muslim and that the Islamic call to prayer is the one of the prettiest sounds on earth? Not every Christian is an evangelist, true, but there are things God calls us to do -- the things mentioned above, amongst others -- that are all witnesses of Christ. It's how we profess our Christianity in our daily walk, as well as with our mouths that speaks to others. If Obama is a Christian, why do so many Americans -- and others throughout the world -- believe him to be otherwise when they consider the way he lives, talks, treats others and governs? Where is the impression that he is a Christian for those who are closest to him, or furthest from him?
Another consideration is the people Obama is appointing as his advisors, czars and cabinet members. Does he appoint Christians, or does he appoint Communists, Marxists and other atheists? Does Obama surround himself with solid Christian counsel, or does he surround himself with those who hate the Lord? If he surrounds himself with those who hate the Lord, where are the converts Obama has made with his Christian witness? Where are the people saying that Obama's Christian leadership and godly counsel helped save their marriage, or that his prayer brought healing to their child's illness? Where is the "cloud of witnesses" to attest to Obama's Christianity? Who does he surround himself with and when do they become his "cloud of witnesses" to Obama's love of Jesus Christ, Obama's Lord and Savior?
When President Bush was in office, he attended a Christian church regularly and few doubted he was a Christian. He spontaneously prayed with people, he was approachable and people knew he cared. He quoted the Bible not just in prepared speeches, but in his everyday language. President Bush was a known entity and hated for being so outspoken a Christian. Do a Google® search for "George W. Bush Christian" and see how many sites come up that spew hatred for Bush and his Christianity. It amazed me. When you look at Obama's supposed Christianity, then it's we who have to take Obama's word for it, and -- even though he mocks us and he scorns us and denies America is a Christian nation -- we are supposed to take Obama's word that he is a Christian.
I beg to differ. When the Bible tells us what to look for, what facts to consider, what obedience is (tithing, praying, fasting, witnessing, etc.), and we see none of the fruit the Bible tells us to take into consideration, then we can make an educated -- and Biblical -- decision that Obama is not a Christian. After all, what true Christian would ever have the "slip up" of saying, "my Muslim faith"? I think that speaks volumes in and of itself.
So, is Obama a Christian? I think the Bible makes the final call on that. In Matthew 7:21 it says, "Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven." I think "Lord, Lord" is Obama's act: doing the will of God "which is in heaven" is Obama's failing.
