Ronald Reagan famously stated, "The trouble with our Liberal friends is not that they're ignorant; it's just that they know so much that isn't so."
If you have engaged with anyone that is a liberal atheist, you will have first hand experience with this. The Bible tells us:
"Since they thought it foolish to acknowledge God, he abandoned them to their foolish thinking ..." Romans 1:28.
Proverbs 14:12 There is a way which seems right to a man, But its end is the way of death.
Psalm 14:1 The fool says in his heart, “There is no God.”
We are already seeing the great deception, "For this reason God sends them a powerful delusion so that they will believe the lie." 2 Thessalonians 2:11
Truth holds no weight with them, they are wise in their own eyes (Proverbs 3:7) and can back up their positions with as many sources as you. They are blind and ignorant and their hearts are hardened. By rejecting God, they become foolish in all of their ways. They have on glasses that show them a world that does not exist; they are ripe for deception, and doomed to judgement.
It is the ultimate mercy and restraint of a loving God that stays His hand, that allows evil to flourish, and does not demonstrate his infinite power in righteous anger against the wickedness and depravity that has been unleashed upon this earth. He will not be silent forever and I pray that any whom we have loved and witnessed to will have a chance but I fear it is already too late.
