Anticrastinate 

Labeled as the opposite of the word "Procrastinate". Used mostly by students to challenge procrastination, yet it leads to an extremer version of procrastination.

life before Twitter

Until I started tweeting, anticrastination was amongst my few virtues but, alas, no more.

Not Anti-God, but Anti-Christ 

When opponents of Christianity are hell-bent to devaluing Jesus’ deity, the cross, and His power to forgive all sins, by telling others that Jesus is not the Son of God, but just one of the prophets in the Bible—the lie that their place in paradise is dependent on their good deeds and performing lifelong rituals on earth to an impersonal God rather than through their faith in Jesus’ grace alone and establishing a personal relationship with Him.

It’s not surprising that many religious leaders, who are not anti-God, but anti-Christ, wouldn’t want their followers to know that Jesus’ blood shed on the cross (and not the blood of bulls and goats) is able to forgive all their sins and cleanse them from all unrighteousness, and that through His grace (unmerited favor) by faith (and not through works and rites) that they have eternal life.
