Realize that you are a sinner in need of salvation.
“For all have sinned and come short of the glory of God.” Romans 3:23
Realize that because you are a sinner, you deserve spiritual death,
i.e. separation from God for eternity in the lake of fire.
“Wherefore as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned.” Romans 5:12
Realize that you cannot save yourself.
“Not by works of righteousness which we have done, but according to His mercy He saved us.”—Titus 3:5
Realize that God will forgive your sin and save you if you will repent of your sin
and accept what Jesus did for you as the only way of salvation.
“Jesus saith unto him, I am the way, the truth, and the life; no man cometh unto the Father, but by me.” John 14:6
“Neither is there salvation in any other; for there is none other name under heaven given among men, whereby we must be saved.” Acts 4:12
“For whosoever shall call upon the name of the Lord shall be saved.” Romans 10:13
