It can’t be explained because the understanding has to be earned.
Some things we have accepted as automatic, really aren’t. We must be grateful and never take God’s wisdom for granted.
Contentment belongs, and therefore, comes from God. The enemy tries to pawn it off as personality traits but it’s far more than that.
Contentment is a treasure we find while reading His word,
Searching for his guidance on bended knees,
Reverencing his presence in song.
It is as if foraging through an old treasure chest and coming upon the rarest of gems. It must not be belittled. Phil 4:11-12
I hope you find it, Oh do I ever.
