(Key scriptures taken from ROMANS, New King James Version)
For all have sinned, and fall short of the glory of GOD.
Therefore, just as through one man sin entered into the world, and death through sin; and thus death spread to all men, because all sinned.
For the wages of sin is death; but the gift of GOD is eternal life in Christ Jesus our Lord.
But GOD demonstrates HIS own love toward us, in that while we were still sinners, Christ died for us.
That if you confess with your mouth the Lord Jesus, and believe in your heart that GOD has raised Him from the dead, you will be saved.
For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation.
For whoever calls on the name of the Lord shall be saved.
You must first have a repentant heart in order to be saved. This is only the beginning of salvation. You must make a commitment to live a life that pleases GOD.
