Explaining the Gospel works the same way. We first start with the foundational teaching that God is Creator, and that sin and death entered the world, as recorded in Genesis. That the foundational knowledge needed to understand the next part—the ‘walls’—that God sent His Son to die on the Cross and be raised from the dead, because death is the penalty for sin. This is the power of the gospel, and why Christ can offer us the free gift of salvation. Then we put on the ‘roof.’ One day there’s going to be a new heaven and a new earth. So there we have the gospel, beginning with Genesis and ending with Revelation. It’s really like building a house from the foundation to the roof” (Gospel Reset by Ken Ham, p.40-41).
“174 Therefore let everybody know that it is his chief duty, on pain of losing divine grace, to bring up his children in the fear and knowledge of God, and if they are gifted to give them opportunity to learn and study so that they may be of service wherever they are needed.
175 If this were done, God would richly bless us and give us grace so that men might be trained who would be a benefit to the nation and the people. We would also have soundly instructed citizens, virtuous and home-loving wives who would faithfully bring up their children and servants to be godly. 176 Think what deadly harm you do when you are negligent in this respect and fail to bring up your children to usefulness and piety. You bring upon yourself sin and wrath, thus earning hell by the way you have reared your own children, no matter how devout and holy you may be in other respects. 177 Because this commandment is disregarded, God terribly punishes the world; hence there is no longer any civil order, peace, or respect for authority. We all complain about this state of things, but we do not see that it is our own fault. Because of the way we train them, we have unruly and disobedient subjects. (Large Catechism -Tappert, p. 388).
