Sanctification remains the key to usefulness in this kingdom. God requires and demands man’s sanctification to guarantee His usefulness. Jeremiah 15:19 “…and if thou take forth the precious from the vile, thou shalt be as my mouth…” Sanctification makes you as one with God. It alligns you with God. Isaiah 6:5-8; 52:11; Zechariah 3:1-8, Psalm 15:1-5; 24:3,4 ; 4:3, Ecclesiastes 9:8, II Timothy 2:19-22, Proverbs 25:4 Keep your vessel constantly clean to keep God constantly at work. God detest unclean environment. What God is looking for first is how we live, not what we do. It is our cleanliness before our activities. God has no problem working the moment he can find clean vessels to work through, nothing less than pure vessels is acceptable to him. Clean up and God will show up. Exodus 19:11 Daily cleansing is the guarantee for daily usefulness.
