Matthew 10:7-87 And as you go, preach, saying, ‘The kingdom of heaven is at hand.’ 8 Heal the sick, cleanse the lepers, raise the dead, cast out demons. Freely you have received, freely give. Acts 10:34-38
34 Then Peter opened his mouth and said: “In truth I perceive that God shows no partiality. 35 But in every nation whoever fears Him and works righteousness is accepted by Him. 36 The word which God sent to the children of Israel, preaching peace through Jesus Christ—He is Lord of all— 37 that word you know, which was proclaimed throughout all Judea, and began from Galilee after the baptism which John preached: 38 how God anointed Jesus of Nazareth with the Holy Spirit and with power, who went about doing good and healing all who were oppressed by the devil, for God was with Him.
1 Cor 4:20
For the kingdom of God is not a matter of words but of power.
