The way of the Lord is strength

"Perhaps thou findest thy duty of thy calling too heavy for thy weak shoulders, make bold by faith to lay the heaviest end of thy burden on God's shoulder, which is thine (if a believer) as sure as God can make it by promise.   When at any time thou art sick of thy work, and ready to think with Jonas to run from it, encourage thyself with that of God to Gideon, whom he called from the flail to thrash the mountains, ‘Go in this thy might,’ hath not God called thee?   Fall to the work God sets thee about, and thou engagest his strength for thee. The way of the Lord is strength.   Run from thy work, and thou engagest God's strength against thee; he will send some storm or other after thee to bring home his runaway servant.   How oft hath the coward been killed in a ditch, or under some hedge, when the valiant soldier stood his ground and kept his place got off with safety and honor?  ... In a word, Christian, rely upon thy God, and make thy daily applications to the throne of grace for continual supplies of strength; you little think how kindly he takes it, that you will make use of him, the oftener the better, and the more you come for, the more welcome."

Gurnall,  The Christian in Complete Armour
