Neither you nor I could ever know anything about Christ, or believe on Him, and have Him for our Lord, unless it were offered to us and granted to our hearts by the Holy Spirit through the preaching of the Gospel [1 Corinthians 12:3; Galatians 4:6]. The work of redemption is done and accomplished [John 19:30]. Christ has acquired and gained the treasure for us by His suffering, death, resurrection, and so on [Colossians 2:3]. But if the work remained concealed so that no one knew about it, then it would be useless and lost. So that this treasure might not stay buried, but be received and enjoyed, God has caused the Word to go forth and be proclaimed. In the Word He has the Holy Spirit bring this treasure home and make it our own. 39 Therefore, sanctifying is just bringing us to Christ so we receive this good, which we could not get ourselves [1 Peter 3:18]. --LC, Article III.

The only subject the Christian parent is ultimately concerned with is their child's learning of God's Word for faith and salvation. All other knowledge and wisdom have a supporting role in life and love.

Many crises in home, congregation, and state are caused by the hubristic thinking that we’ve reached the peak of civilization, knowledge, and wisdom and have nothing left to learn.
