requires it, but because they want to do so! "They did not like to retain God in their knowledge" (Romans 1:28), and so "Professing to be wise, they became fools," (Romans 1:22).
For those who really want to know God, He has revealed Himself to us through His Son, Jesus Christ, Who came to live with us as God in the flesh (John 1:1-5; 1:14; Matthew 1:23). Jesus showed us God's will for our lives, died for us on the cross, was buried, and arose from the dead on the third day (I Corinthians 15:1-7)! He gives spiritual life to those who receive Him in faith and obey His Word.
Man's Problem -- SIN!
Something is radically wrong with the human race. They hurt each other and themselves. They rob and rape. They swear and steal. They murder and molest. Nations oppose nations, and there are always wars and rumors of wars.
The trouble with man is sin. Our greatest enemy is not ignorance or inflation, debt or deflation, disease or death. Our greatest enemy is sin in the hearts of people. The confusion, suffering and sorrow in the world comes because of sin.
Sin separates us from God (Isaiah 59:1-2). Nothing else can separate us from God, but sin has great power over us. But what is sin? What are its results in human life? Is there any way of escape from its consequences?
Sin is Universal
First, we see that sin is universal. All people have sinned. "for all have sinned and fall short of the glory of God," (Romans 3:23). "If we say that we have no sin, we deceive ourselves, and the truth is not in us...If we say that we have not sinned, we make Him a liar, and His word is not in us" (I John 1:8,10). The fact that "everybody does it" will not excuse us. No race, no tribe, no nation is immune from sin. We are all guilty because sin is universal, found in every century and in every culture!
Because of sin in human life, man's relationship to God is described as being "ungodliness" (Romans 1:18). To be ungodly is to be anti-God. Sin is therefore living without God, or leaving God out, or living in rebellion against God. It is living contrary to God's law for our life.
