(“BSO” stands for Bible study outline. For an explanation of what I mean by that, see here.)
Consider these four New Testament voices (of course, the second, third, and fourth are all echoes of the first) and how firm and united are these voices against any quantity of worry, anxiety, or fear.
Jesus: John 14:27 (“…Do not let your heart be troubled, nor let it be fearful.”)
Paul: Philippians 4:6 (“Be anxious for nothing…”)
Peter: 1 Peter 5:7 (“casting all your anxiety on Him…”)
John: 1 John 4:18 (“There is no fear in love…”)
