Postmill Parenting (The Well-Pleased Father #2)

October 6, 2024 • Toby Sumpter • Isaiah 59:16–21

Postmillennialism is the doctrine that teaches that over the course of history, the Great Commission will be accomplished: the nations will be discipled, the earth will be full of the knowledge of the Lord as the waters cover the sea, that God will save the world before Christ returns in glory. This will be accomplished not by force of arms or political maneuvering, but by the preaching of the gospel and the work of the Spirit. 

In many ways this is simply an application of the doctrine of sanctification applied to history. Sanctification is the doctrine of growth in Christ: “Being confident of this very thing, that He which began a good work in you will perform it until the day of Jesus Christ” (Phil. 1:6, cf. Eph. 1:13-14, 2 Cor. 3:18, 2 Pet. 1:3-4). This growth in grace is driven by faith not by works (Gal. 3:1-5). And therefore, Christian parenting is no different. 

Parenting in faith is very different from parenting in fear. Faith is the substance of things hoped for, the evidence of things not seen (Heb. 11:1). But it is not merely optimism or high hopes; it is faith in the promises of your Father. 

The Text: “…As for me, this is my covenant with them, saith the LORD; My spirit that is upon thee, and my words which I have put in thy mouth, shall not depart out of thy mouth, nor out of the mouth of thy seed, nor out of the mouth of thy seed’s seed, saith the LORD, from henceforth and forever” (Is. 59:16-21).
