4. The last important point for the strengthening of our faith is, that we let God work for us, when the hour of the trial of our faith comes, and do not work a deliverance of our own. Wherever God has given faith, it is given, among other reasons, for the very purpose of being tried. Yea, however weak our faith may be, God will try it; only with this restriction, that as in every way, He leads on gently, gradually, patiently, so also with reference to the trial of our faith. At first our faith will be tried very little in comparison with what it may be afterwards; for God never lays more upon us that He is willing to enable us to bear. Now when the trial of faith comes, we are naturally inclined to distrust God, and to trust rather in ourselves, or in our friends, or in circumstances. We will rather work a deliverance of our own somehow or other, than simply look to God and wait for His help. But if we do not patiently wait for God’s help, if we work a deliverance of our own, then at the next trial of our faith it will be thus again, we shall be again inclined to deliver ourselves; and thus with every fresh instance of that kind, our faith will decrease; whilst on the contrary, were we to stand still, in order to see the salvation of God, to see His hand stretched out on our behalf, trusting in Him alone, then our faith would be increased, and with every fresh case in which the hand of God is stretched out on our behalf in the hour of the trial of our faith, our faith would be increased yet more. Would the believer, therefore, have his faith strengthened, he must especially, give time to God, who tries his faith in order to prove to His child, in the end, how willing He is to help and deliver him, the moment it is good for him.
Though older, these timeless truths from George Mueller can help us grow in our faith.
