THE GRACE OF GOD
"For the grace of God that bringeth salvation hath appeared to all men, teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and Godly, in this present world" (Titus 2:11,12).
"For the law was given by Moses, but grace and truth came by Jesus Christ" (John 1:17).
A Christian, to keep saved, must walk with God and keep himself in the love of God (Jude 21) and in the grace of God. The word "grace" means "favor." When a person transgresses and sins against God, he loses his favor. If he continues to commit sin and does not repent, he will eventually be lost and cast into the lake of fire. (Read John 15:2, 6; 2 Peter 2:20-21). Jude speaks of the backsliders of his day, and their reward. (Also, read Hebrews 6:4-6).
"For by grace are ye saved through faith; and that not of yourselves; it is the gift of God" (Eph. 2:8).
