Not now does not mean never.
Isaiah 40:31 (AMPC)
But those who wait for the Lord [who expect, look for, and hope in Him] shall change and renew their strength and power; they shall lift their wings and mount up [close to God] as eagles [mount up to the sun]; they shall run and not be weary, they shall walk and not faint or become tired.
1 Peter 5:6-7 (AMPC)
Therefore humble yourselves [demote, lower yourselves in your own estimation] under the mighty hand of God, that in due time He may exalt you. Casting the whole of your care [all your anxieties, all your worries, all your concerns, once and for all] on Him, for He cares for you affectionately and cares about you watchfully.
