It seems to me that you could be referring to

2 Thessalonians 2:11
Because of this, God sends a deceptive influence over them so they will wander from the truth and believe the lie.

This passage is reffering to the anti-christ or the people that reject following the TRUTH (JESUS is the WAY, The TRUTH, and The LIFE) GOD is saying in the above passage, 'all'right you people rejected MY SON for long enough, so now I am going to allow you guys to chase your shadows.'

But it sounds like you are talking about

Romans 1:28
Furthermore, just as they did not think it worthwhile to retain the knowledge of God, so God gave them over to a depraved mind, so that they do what ought not to be done.

However in both cases a similar point is made by GOD, and the point is that none of us know what tomorow holds, none of us should put off the most important piece of business...because as we have seen: GOD might get fed up with our anticts!

2 Corinthians 6:2
For he says, "In the time of my favor I heard you, and in the day of salvation I helped you." I tell you, now is the time of God's favor, now is the day of salvation.

(I want to say Thank You for asking this question, because among other things, your question caused me to further search the scriptures! :)
