CONTINUE In The Truths

Abiding in truths does not just stop at what you have learnt and believed in. It's not a 'been-there-done-that' event.

We have to actively CONTINUE (abide, stay, remain) in the truths.

But as for you, continue in what you have learned and have firmly believed, knowing from whom you learned it... - 2 Tim 3:14

Paul taught that. So did John. John taught that multiple times in the epistles that he wrote.

The day when we do not actively continue in truths is the day when we will start straying away.
