I will pour My Spirit upon thy seed, and My blessing upon thine offspring. -Isaiah 44:3
Our dear children have not the Spirit of God by nature, as we plainly see. We see much in them which makes us fear as to their future, and this drives us to agonizing prayer. When a son becomes specially perverse, we cry with Abraham, “Oh, that Ishmael might live before thee!” We would sooner see our daughters Hannahs than empresses. This verse should greatly encourage us. It follows upon the words, “Fear not, O Jacob, my servant,” and it may well banish our fears.
The Lord will give His Spirit; will give it plentifully, pouring it out; will give it effectually, so that it shall be a real and eternal blessing. Under this divine outpouring our children shall come forward, and “one shall say, I am the Lord’s; and another shall call himself by the name of Jacob.”
This is one of those promises concerning which the Lord will be inquired of. Should we not, at set times, in a distinct manner, pray for our offspring? We cannot give them new hearts, but the Holy Spirit can; and He is easily to be entreated of. The great Father takes pleasure in the prayers of fathers and mothers. Have we any dear ones outside of the ark? Let us not rest till they are shut in with us by the Lord’s own hand.
