The world will try to convince you that you're not enough. You don't have enough money, no matter how much your bank account grows.
They'll say you're not pretty enough.
You're not smart enough.
You don't know the "right" people or you're not influential enough. And you may start to believe these things and say them to yourself. And tell them to others.
Please note that God is "able to make every grace OVERFLOW to you, so that in every way, always having EVERYTHING you need, you may EXCEL in every good work" (2 Corinthians 9:8).
With God, you are more than enough.
