Why are so many "Christians" abandoning our "Blessed Hope" the rapture?

1. Thessalonians 4
Isaiah 26:19-21
Titus 2:12 It teaches us to say “No” to ungodliness and worldly passions, and to live self-controlled, upright and godly lives in this present age, 13 while we wait for the blessed hope—the appearing of the glory of our great God and Savior, Jesus Christ, 14 who gave himself for us to redeem us from all wickedness and to purify for himself a people that are his very own, eager to do what is good. 15 These, then, are the things you should teach. Encourage and rebuke with all authority. Do not let anyone despise you.
