His grace is sufficient.
The Lord says His grace is all I need (2 Cor. 12:9-10), because His strength (aka His power, His might) is made perfect in my weakness (my lack of strength, my powerlessness). Without God's merciful favor upon me, do I really have "power" anyway? Do the feats, accomplishments, and works I do in this life hold any lasting meaning anyway, without God? (Eccl. 3:18-22). They do not. But with God, resting in His strength and depending on His mercy, I can rejoice in the works I do here, whatever they may be, for I do them all for Him, He may be glorified (Col. 3:17). This thought reminds me of something I once read from Charles Spurgeon, in his sermon on Luke 10:42:
I would be nothing but what he makes me,
I would have nothing but what he gives me,
I would ask nothing but what he promises me,
I would trust in nothing but what he has done for me, and
I would desire nothing but what he has prepared for me.
Is God's grace enough for you?
