The Lord is longsuffering, hoping all men will be saved (1 Timothy 2:3-4).
We embrace that truth, but we aren’t as fond of the “warning” passages.
For example, God knows when He's given men ample opportunities to repent. When they stand firm in their wickedness and rebellion, God “gives them over” to their sins.
Romans 1:18-32 describes wicked people and says, “God gave them over in the sinful desires of their hearts to sexual impurity” (24),“God gave them over to shameful lusts” (26), and “God gave them over to a depraved mind” (28).
In 2 Thessalonians 2:5-12, God promises to send “a powerful delusion” to the unrepentant so they believe the lies of the Anti-Christ.
“Popular” Christianity(1) sidesteps these warnings thinking they don’t sound “loving.” But God did not sidestep these warnings, and He loves perfectly.
We cannot judge when someone has reached this point of "giving over," but there are important reasons to warn people that it can happen if they continue in their rebellion against God.
(1) One reason for the trend in Christianity is the popular use of the phrase "unconditional love." It is a description for God's love not found in Scripture because it leads people to believe there are no conditions on God's blessings, salvation, and love. These passages and hundreds of others prove that while God's love can't be earned, and He offers it to all men, He does not strive forever with unrepentant men and women (Genesis 6:3).
