Matthew 9:35-38 …what Jesus did…
35 And Jesus went about all the cities and villages, teaching in their synagogues, and preaching the gospel of the kingdom, and healing every sickness and every disease among the people.
It is noteworthy that Yeshua did not preach “taking Jesus into your heart”, He preached the Kingdom of Heaven. This is the power and majesty of YHWH and the glory to come. This the covenant made to Abraham, affirmed in Isaac and assured in Jacob, and to be sealed in Yeshua.
36 But (moreover) when he saw the multitudes, he was moved with compassion (feel sympathy, to pity) on them, because they fainted (to relax, be torn down), and were scattered abroad, as sheep having no shepherd.
37 Then saith he unto his disciples, The harvest truly is plenteous, but the labourers (teachers) are few;
38 Pray ye therefore the Lord of the harvest, that he will send forth labourers (teachers) into his harvest.
