Certain decrees in the Word of God cannot be disputed because of the Law of Righteousness. Imputed Righteousness is the gift of God. We receive rewards of obedience no matter what other deficiencies we have because of this imputed righteousness. His Spirit helps our infirmities.
The Law of Increase is one of the Laws that govern our righteous walk. The Law of Increase decrees that when we give, it's given back to us, good measure, pressed down, shaken together and running over. ITS the LAW!
