'Devotion' in the Bible

So, even though I wrote to you, it wasn't because of the man who did the wrong or because of the man who was hurt. Instead, I wrote to you so that your devotion to us might be made perfectly clear to you before God.

However, I am afraid that just as the serpent deceived Eve by its tricks, so your minds may somehow be lured away from sincere and pure devotion to the Messiah.
