“No one puts new wine into old wineskins; otherwise the wine will burst the skins, and the wine is lost and the skins as well; but one puts new wine into fresh wineskins” (Mark 2:22).
Those who have answered the call of Christ — to follow after him, while at the same time clinging to or imposing upon others the necessity of Old Testament observances and customs — have grossly misunderstood the freshness, uniqueness, and revolutionary rule of God in Christ Jesus. The old brought only condemnation and exclusion. Not only is it incompatible with the new, but both are ruined when combined. The gospel isn’t God’s patchwork or an attempt at reformation; it is the full expression of his redemptive purposes, revealed in Christ Jesus.
