My secret for remembering the order of the "t" books (and the rest of the New Testament...)
The gospels (Matthew, Mark, Luke, John) and Acts and Romans 1st and 2nd Corinthians.(Just know them, sorry, no trick)
the Paul letters- You know the vowels? A,E,I, O, and U? Tthat's the order of the Paul letters: g"A"lations, Eph"E"sians, Ph"I"lippians, C"O"lossians.... cool huh? A good way that "U" can remember.
(Here comes the "T" part) 1st and 2nd Thessalonians, 1st and 2nd Timothy, Titus- they are alphabetical.
and then philemon and Hebrews, (No trick, but it's only two books. You can remember!)
James, 1& 2 Peter, 1,2,3 John (Jesus' three closest friends, the closer they were to Jesus, the higher the number... )
Jude and Revelation!
Happy Resurrection Day, friends!
