Here are some words from Jesus on the subject:
John 8:
39 Jesus saith unto them, If ye were Abraham's children, ye would do the works of Abraham.
40 But now ye seek to kill me, a man that hath told you the truth, which I have heard of God: this did not Abraham.
41 Ye do the deeds of your father. Then said they to him, We be not born of fornication; we have one Father, even God.
42 Jesus said unto them, If God were your Father, ye would love me: for I proceeded forth and came from God; neither came I of myself, but he sent me.
43 Why do ye not understand my speech? even because ye cannot hear my word.
44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
And in Romans 1, we read about those who suppress the truth in unrighteousness. When the truth is revealed to them, they restrain the truth. From there, downward spiral as they step further and further away from God. And there are several steps. God holds them for a certain time, but eventually He has to let them go.
The process starts with suppressing the truth in unrighteousness (Rom 1:18) which results in not glorifying God, being unthankful, empty imaginings, foolish heart being darkened (Rom 1:21).
After a while, God gives them up to uncleanness (Rom 1:24).
After a while, God gives them up to vile affections (Rom 1:26).
After a while, God gives them over to a reprobate mind (Rom 1:28).
The process starts and ends with people rejecting God and God having to let go bit by bit until they become just as Rom 1:28-32 describes.
For those who turn to God and who do not restrain the truth in unrighteousness, God works in their lives to bring them closer and closer to Him. And one day, God is going to finish the work in His people. And then they shall know even as also they are known (1 Cor 13:12) ... then they shall be like Him (the Lord Jesus Christ) for they shall see Him as He is (1 John 3:2).
