William Kelly · Joshua 1-4.

Further we find for the difficulties in the way, which in truth are immense, that God gives proportionate comfort and assurance. — "There shall not any man be able to stand before thee all the days of thy life: as I was with Moses, so I will be with thee: I will not fail thee, nor forsake thee. Be strong and of a good courage." The last words one sees are very emphatic, and even in the first chapter repeated over and over again. Let me ask my brethren whether they have really understood that this is what they are called to, — what we are called to now. Not a few sincere Christians err greatly here. They confound good courage with presumption; that assurance in the Lord with the lowest, basest, proudest feeling of the flesh; mere thoughtless audacity without an atom of believing confidence in God. From presumption may every child of God be kept! On the other hand, God forbid that a child of His should be cheated out of the good courage and single-eyed confidence due to God by that which defames them. No, my brethren; we are called to be strong and of a good courage.
