Tit 2:11 For the grace of God that bringeth salvation hath appeared to all men,
From G1909 and G5316; to shine upon, that is, become (literally) visible or (figuratively) known: - appear, give light.
Joh 1:5 And the light shineth in darkness; and the darkness comprehended it not.
Joh 1:9 That was the true Light, which lighteth every man that cometh into the world.
Joh 1:10 He was in the world, and the world was made by him, and the world knew him not.
Joh 1:11 He came unto his own, and his own received him not.
Rom 1:5 By whom we have received grace and apostleship, for obedience to the faith among all nations, for his name;
Rom 5:2 By whom also we have access by faith into this grace wherein we stand, and rejoice in hope of the glory of God.
Rom 5:17 For if by one man's offense death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ.)
Seems to me, grace is only covering those who receive it?
Tit 2:12 Teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world;
Tit 2:13 Looking for that blessed hope, and the glorious appearing of the great God and our Savior Jesus Christ;
Tit 2:14 Who gave himself for us, that he might redeem us from all iniquity, and purify unto himself a peculiar people, zealous of good works.
Tit 2:15 These things speak, and exhort, and rebuke with all authority. Let no man despise thee.
