Adam loved his kids Cain and Abel. Lamech loved his other sons and daughters. Terah fathered Abram, Nahor, and Haran. Abraham loved Ishmael and Issac. Isaac loved Jacob and Esau.
It was Abel, not Cain. Noah, not the others. Abraham was called out. Issac was the son of promise. Jacob was the one.
The unfolding storyline of the Bible heralds the electing love of the LORD. This is not an issue to shirk away. It is undeniable. It is even thematic. But how should I view the possibility that my children are not elected to salvation?
This is a difficult question. I should view it painfully, humbly, and gratefully:
I should view it painfully because I love my children and I do not want to see them suffer any harm. I love them and I want to protect them.
I should view it humbly because punishment for sin is a punishment that we all should have to pay. My children are guilty. They have sinned against God. The role of creature to Creator supersedes the role of child to parent.
I should view it gratefully because the punishment I should pay has already been paid for me by Jesus Christ on the cross. I should be grateful because he has given children to me as my children–children of parents who embrace the gospel by faith. This is the reality that we live in. I don’t base my theology on the possible-would be-alternative realities. ‘God could do this, he could do that, etc.’ No, no—my theology is based on revelation, what God has done and said he would do, testified to in the Holy Scripture and accomplished in my own life.
God has saved me and my wife. God has given us children. God is making it so that my children hear the gospel all the time from parents who jovially embrace it as the best news in the universe. God has made it–predestined it–that my children have parents who believe the gospel and daily pray that they will believe it too. It did not have to be this way. But this is the way that God has made it. This is the right note that I think paedobaptists and more covenantal perspectives hit on. My children have already received a blessed privilege and everything in reality suggests that they will put their faith in Jesus just like their parents have and continually pray that they will. Everything in this reality suggests that Jesus atoned for their sins on the cross just as he atoned for mine.
Father, please lavish upon my children the grace to worship by the Holy Spirit, glory in Christ Jesus, and put no confidence in the flesh. Amen.
