God's Word convicts the hearts of the Jews:
Jer. 17:1 "The sin of Judah is written with a pen of iron, and with the point of a diamond: it is graven upon the table of their heart, and upon the horns of your altars."
God's Word convicts the hearts of the Gentiles:
Rom. 2:15 "Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another."
God's Word, lived out in the born again believer, convicts all of mankind:
2 Cor. 3:2-3 "Ye are our epistle written in our hearts, known and read of all men: Forasmuch as ye are manifestly declared to be the epistle of Christ ministered by us, written not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshy tables of the heart."
The Holy Trinity is working to save all men:
Jn. 6:44 "No man can come to Me, except the Father which hath sent Me draw him: and I will raise him up at the last day."
Jn. 12:32 Jesus said, "And I, if I be lifted up from the earth, will draw all men unto Me."
Jn. 15:26 " But when the Comforter is come, whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, He shall testify of Me."
IF YOU FAIL TO BELIEVE IN THE LORD JESUS, IT'S ALL ON YOU!
