Jesus says commitment to Him will bring conflict between the closest of family members; fathers and sons, and mothers and daughters. The chief reasons are that Jesus and the light of His expose sin, and that His demand for total commitment inevitably strains relationships with family members who are unbelievers.
Jesus gives His followers very specific instructions as they launched out on their first Gospel mission. They were to preach the Gospel of the kingdom and show the signs and power of the kingdom. They were to not get sidetracked into moneymaking schemes, but depend on the good provision of the Father. They were to keep their focus on the task at hand.
Christ always does what He says He will do. He is absolutely faithful, and this creates faith in our own hearts.
You can’t put new wine into old wine skins, or the new wine bursts the old skins. Nor can Christ be put back into the Old Covenant. You can’t put Him back into the temple, because He is the true temple, the true meeting place between God and man. The new wine of Christ requires a new covenant of grace and a new temple in the body of Christ.
Jesus did not come to call those who see themselves as righteous, but those who we often see as revolting or disgusting; the sinners. This is a great consternation to the self-righteous, because they simply do not see themselves in the light of God’s truth; that they too are sinners, in need of a Savior.
