For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven. Matthew 5:20
The characteristic of a disciple is not that he does good things, but that he is good in his motives, having been made good by the supernatural grace of God. The only thing that exceeds right-doing is right-being. Jesus Christ came to place within anyone who would let Him a new heredity that would have a righteousness exceeding that of the scribes and Pharisees. Jesus is saying, “If you are My disciple, you must be right not only in your actions, but also in your motives, your aspirations, and in the deep recesses of the thoughts of your mind.” Your motives must be so pure that God Almighty can see nothing to rebuke. Who can stand in the eternal light of God and have nothing for Him to rebuke? Only the Son of God, and Jesus Christ claims that through His redemption He can place within anyone His own nature and make that person as pure and as simple as a child. The purity that God demands is impossible unless I can be remade within, and that is exactly what Jesus has undertaken to do through His redemption. Oswald Chambers, My Utmost for His Highest
