God commanded all men everywhere to repent. This repentance is a change of mind that agrees with God that all are sinners, and also agrees with what Jesus did for us on the cross. And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house. His resurrection assures that the believer can claim everlasting life when Jesus is received as Savior. For whosoever shall call upon the name of the Lord shall be saved.
Call is to ask.
The name of the Lord is Jesus. Surely, you realize you are a sinner. Right now, wherever you are, repenting lift your heart to God in prayer. I believe Jesus was my substitute when He died on the cross. I believe His shed blood, death, burial, and resurrection were for me.
