The reason I am a Christian is because I don’t know how to disprove the proof for God and who God is.
I see trillions of cause and effects in nature, and no hard evidence of something from nothing, so this evidence is an overwhelming preponderance of evidence beyond a reasonable doubt to know that the first event of the universe like all the events of the universe has a cause and can’t come from nothing (i.e. non-existence). Non-existence can't produce anything as it does not exist. Claiming non-existence caused existence belongs in the loony bin!
And there can’t be an infinite regress of cause and effects in nature either, because if there had been, you would have, by that very definition, an eternity to come into being before now, so you should have already happened. And you should never have existed because a past eternity of nature would go on forever never reaching this point of your existence. So a past eternity of nature is inherently contradictory and a man-made superstition.
Therefore, nature needs a cause outside of itself, outside of time and space, being uncreated whom we call God. But God can’t have morals below our own so He must have perfect morality. He can't be inaccessible (an absentee landlord, i.e. deistic) for that is beneath us, contrary to our own way of being, for we entreat our fellow man in need or at least we should. He is not impersonal for we are personal beings. He must have a mind because a mind is needed to create a mind: the lesser can't produce the greater: a mind can't originate from lesser non-consciousness. He has self-consciousness, because consciousness is needed to create consciousness in creatures. Life has a soul, that divine spark of life when spirit makes contact with the body, which can't be explained solely by the dust of the ground by itself.
There are only 3 religions or faiths on the planet that are accessible and pervasive enough worth taking a gander at for a personal God: Hinduism, Islam and Christianity. We know Islam is false because you can’t come along six centuries later without anything to support your claim that Jesus never died on the cross or even went to the cross. Otherwise, you could spout off anything as being the truth. But we are evidentialists not suppositionalists.
Hinduism fails because its god is said to be amoral which is below our own morality. And reincarnation, coming back as a chicken if you are overly sinful, doesn’t tackle sin expediently in this life since you always get another chance as though you might change your mind later. But, really, would you? Surely, you have already made up your mind and don't need another life to decide let alone a billion years to decide. And who dare hold a chicken responsible for man's eternal well being? Silly nonsense! Who do you know over the age of 40 who ever gave their life to Christ? They have had more than enough time in this life alone.
That leaves only Christianity which, therefore, must be true. And it is proves itself to be true, because there is no naturalistic explanation to account for the eyewitness testimony of the Apostles in various group settings. Group hallucinations are impossible. The swoon theory wouldn’t make Jesus look like a risen Messiah to convince anyone He is God. The original eyewitness Apostles are human beings, and human beings don’t willingly die for what they know is a lie so they truly believed it. They were not liars. So their position must be accounted for and not blithely discounted. Since there is no mental problem and they did not lie, it must be true! Legends theory breaks down because there was not enough time to develop. Jesus had more sources written about Him within 150 years of His death than any 10 figures in antiquity combined. The highest standard of evidence is applied in the 66 books of the Bible! And the earliest still surviving papyri are closer to the events of Scripture than for any other person in antiquity. There are at least 15 papyri from the late first century and from the second century of the NT. If Jesus didn’t do what He did then nobody did anything in antiquity and human beings would not exist. Christ Jesus was a liar, lunatic or God. Since He was not a liar nor a lunatic, He has to be God. No other option avails itself.
This is how we know Jesus is God the Son and Jesus entered His creation to atone for the sins of the world to save people; ergo, whosoever believes in Him shall not perish but receive everlasting life. It is everyone's free choice to want to be eternally separated from the love of God and God Himself or to accept His saving grace. This is God's redemptive design. At the center of the New City will be Jesus (in person) with God the Father (in spirit) and no more need of the throne for they will be the center thereof. All those who reject His love and mercy go to Hell -- a perfectly designed domain or dwelling place for people that need to be locked up in jail forever.
A choice that is not for Jesus is a choice against Him. Shutting your mind down in God's eyes is not a valid excuse. He requires you active participation for He did not make you zombies.
