“But if I cast out deuils by the Spirit of God, then the kingdome of God is come vnto you.”
1611 King James Version (KJV)
Mt 12:28 If I cast out devils by the Spirit of God, etc. If it is the power of God manifest in me, then it demonstrates that I am the expected Messiah King, the Son of David, of whom the multitude spoke. See Mt 12:23.
