"If thou wilt return, 0 Israel, saith the Lord. . . ."  Jeremiah 4:1

The battle is lost or won in the secret places of the will before God, never first in the external world. The Spirit of God apprehends me and I am obliged to get alone with God and fight the battle out before Him. Until this is done, I lose every time.

"And He is the propitiation for our sins: and not for ours only, but also for the sins of the whole world." 1 John 2:2

The key to the missionary message is the propitiation of Christ Jesus. Take any phase of Christ's work - the healing phase, the saving and sanctifying phase; there is nothing limitless about those. "The Lamb of God which taketh away the sin of the world! " - that is limitless. The missionary message is the limitless significance of Jesus Christ as the propitiation for our sins, and a missionary is one who is soaked in that revelation.
