Proclaim the kingdom of God AND perform healing.
And He called the twelve together, and gave them power and authority over all the demons and to heal diseases. And He sent them out to proclaim the kingdom of God and to perform healing. (Luke 9:1-2)
“Jesus while He was upon the earth healed the sick and raised the dead, not merely to typify a spiritual healing and quickening, but to prove that He was indeed the promised Deliverer by destroying the works of the devil, and also to give a fore-taste and a shadow of the ultimate effect of His redemption upon the whole man, body and soul.
And thus we find in the New Testament that the healing of the sick and the preaching of the Gospel of the Kingdom are almost always co-joined, and are so spoken of as though they meant the same thing.” (Thos Erskine; Brazen Serpent, p. 272)
