Some verses that come to mind.
John 12:32 KJVS
[32] And I, if I be lifted up from the earth, will draw all men unto me.
I always knew about God and Jesus. I believed in them since a child, but there wasn't a personal relationship. I didn't truly know the Lord until the Holy Ghost enlightened this blind man to the fact that I was dead in sin and needed a Saviour. As He enlightened me, he drew me with cords of love. But many times I rejected him. Later on in life while in the midst of the church and Christ, the Holy Ghost spoke to me and begin to draw me to himself. I was singing by the piano with others and it didn't really seem like it was right to the natural man, but as I lingered at the piano procrastinating coming to the Lord, the Spirit seemed to start fading away or getting weaker as the Master passed on by. A fear came over me and I felt this could be my last chance. So, I took a few steps and fell at the altar willing to turn from self and turn to Christ. The burden was lifted and the Holy Spirit moved in.
John 16:7-8 KJVS
[7] Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you. [8] And when he is come, he will reprove the world of sin, and of righteousness, and of judgment:
John 3:14-16 KJVS
[14] And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: [15] That whosoever believeth in him should not perish, but have eternal life. [16] For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
2 Peter 3:9 KJVS
[9] The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
I feel by what I read, comparing scripture, and experience that God uses the Holy Spirit to convict us of sin and reveal to us who we are. I believe we must come to him as he speaks or draws us to himself. How shall we escape if we neglect such a great salvation. Neglecting salvation seems to be not excepting Christ when he calls. If we neglect to do something, we fell to do what we know needs to be done.
