Repentance and Oil
Mark 6:12 And they went out, and preached that men should repent.
Has the gospel message changed? They did not yet know of the death and resurrection of their Lord for sins. They preached the kingdom, so do we. Through Jesus we enter the kingdom of God. They also preached repentance from sins. We should too, for it seems that many want to be "saved', but do not want to change. Many never become His disciples and learn of him. Are we teaching them after salvation?
Mat 28:18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
Mat 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
Mat 28:20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
Jesus gives us all the power needed through the Holy Spirit and His word. We must follow His commands and make Him Lord of our life. Go, baptize, teach. Baptism includes repentance and acceptance of Jesus as Lord. We are saved through faith in Jesus and the infilling of the Holy Spirit. If no repentance? There probably is no Holy Spirit and no hunger for God's word.
Mark 6:13 And they cast out many devils, and anointed with oil many that were sick, and healed them.
Get out the oil. The same Spirit works in those who have received Jesus and are His disciples.
