WHY MAN'S WAY OF SALVATION DOES NOT WORK:

1.  None of these things will give you a divine nature.

2.  None of these things will pay for your sins, the penalty for sin is death.  Someone must die for your sins.

3.  None of these things will earn the perfect righteousness that God requires.  That is why the Bible teaches:
"For by grace are ye saved through faith; and that not of yourselves:  it is the gift of God:  not of works, lest any man should boast" (Ephesians 2:8,9).
"Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and the renewing of the Holy Ghost" (Titus 3:5).

MAN CAN'T REACH GOD, BUT GOD HAS REACHED DOWN TO MAN.

Jesus Christ lived a perfect life.  He always obeyed God's laws and He never one time sinned. When Jesus Christ died on the cross He paid for all of our sins.

"For when we were yet without strength, in due time Christ died for the ungodly.  But God commendeth his love toward us, in that while we were yet sinners, Christ died for us" (Romans 5:6, 8).

"For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened by the Spirit" (I Peter 3:18).
