Let us watch against unbelief, pride, and self-confidence. If we go forth in our own strength, we shall faint, and utterly fall; but, waiting on the Lord, out of weakness we shall be made strong. Having our hearts and our hopes in heaven, we shall be carried above all difficulties, and be enabled to press forward and lay hold of the prize of our high calling in Christ Jesus.
Matthew HenryWe have no sufficient strength of our own. All our sufficiency is of God. We should stir up ourselves to resist temptations in a reliance upon God's all-sufficiency and the omnipotence of his might.
Matthew Henry
