For to the one who has, more will be given, and he will have an abundance, but from the one who has not, even what he has will be taken away. -Matthew 13:12
When the Lord has given to a man much grace, He will give him more. A little faith is a nest egg; more faith will come to it. But then it must not be seeming faith, but real and true. What a necessity is laid upon us to make sure work in religion and not to profess much, and possess nothing! For one of these days the very profession will be taken from us, if that be all we have. The threatening is as true as the promise.
Blessed be the Lord, it is His way when He has once made a beginning to go on bestowing the graces of His Spirit, till He who had but little, and yet truly had that little, is made to have abundance. Oh, for that abundance! Abundance of grace is a thing to be coveted, It would be well to know much but better to love much. It would be delightful to have abundance of skill to serve God but better still to have abundance of faith to trust in the Lord for skill and everything.
Lord, since Thou hast given me a sense of sin, deepen my hatred of evil. Since Thou hast caused me to trust Jesus, raise my faith to full assurance. Since Thou hast made me to love Thee, cause me to be carried away with vehement affection for Thee!
