Good morning Unbeliever,
I don't say there is no God, merely that I am not aware of there being any God. The color of the earth and various forms of life on it do not tell me there is a God, and I'm not ignoring my conscience. In fact, it is my conscience that compels my unbelief. Anything else would be dishonest.
"I can't ignore creation, my conscience, and what the Bible says." - Davies; Good, I would never tell you to do otherwise. - Unbeliever
Because you say that creation doesn't tell you God exists, your unbelief then tells God He is a liar, and shows that you are ignoring all three: creation, conscience, and the Bible. If you violate the conscience long enough, a person can normalize any behavior.
1 John 1:10
New King James Version (NKJV)
10 If we say that we have not sinned, we make Him a liar, and His word is not in us.
Romans 1:18-23
New King James Version (NKJV)
God’s Wrath on Unrighteousness
18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness, 19 because what may be known of God is manifest in them, for God has shown
it to them. 20 For since the creation of the world His invisible
attributes are clearly seen, being understood by the things that are made,
even His eternal power and Godhead, so that they are without excuse, 21 because, although they knew God, they did not glorify
Him as God, nor were thankful, but became futile in their thoughts, and their foolish hearts were darkened. 22 Professing to be wise, they became fools, 23 and changed the glory of the incorruptible God into an image made like corruptible man—and birds and four-footed animals and creeping things.
How can I keep the first commandment when I don't believe in God?
Even if you did believe in God, you would find you couldn't keep the first Commandment.
Actually, I don't feel like I have that big a problem with the last five. I don't murder, adulterate, or steal, and I generally don't lie or covet. My problems are more in the area of anger and a lack of empathy. I do think it is a good idea to remind myself of these so that I can strive for improvement. But again, without God there is no sin, only wrong and perhaps evil. I know I am often wrong, and evil on occasion. But it doesn't matter how bad I am, if there is no God, then there is no point in coming to the cross and having faith in Jesus.
You may not
feel the Commandments are a problem, but they are. You say you have problems with anger and a lack of empathy (that nailed me), but Jesus said if you are angry with your brother without cause or say 'You fool!', you'd be in danger of hell fire, Matthew 5:22. The Bible teaches us that if we hate our brother, then we are murderers, 1 John 3:15. God not only looks on the outside, what we do, but He also looks on the inside, what we think. If you look at a woman to lust after her, then you are an adulterer, Matthew 5:28. If you have stolen or lied in your entire life, those sins need to be accounted.
What does Jesus dieing on the cross tell you? If Jesus is who He said He is, then the cross is your indictment. He was innocent, yet even while we were yet sinners, Jesus gave Himself over to the wrath of the Father to pay for our sins (your sin debt is paid for). In order to deny this, you have to say that Jesus was a liar, or you have to say that His disciples were liars despite all but one of them were killed because they would not recant and say, 'Jesus did not rise from the dead.'
We often mistake the patience of God to mean He doesn't exist, He's not concerned with us, or that He may even endorse our sin. One of the reasons why God allows sin is because He wants all men to come to repentance.
2 Peter 3:9
New King James Version (NKJV)
9 The Lord is not slack concerning
His promise, as some count slackness, but is longsuffering toward us,[
a] not willing that any should perish but that all should come to repentance.
What I think you'll find, Unbeliever, if you refuse to believe in the God of the Bible, you will go through life looking for things that will give you temporary satisfaction, and because that is not what life is about, our satisfaction, you will be missing out on the blessings, mercy, and forgiveness that God would give you.
