When Christ died on the cross, He bore the curse required for our disobedience (cf. Deut. 21:23) so that through faith in Him we can receive the blessings merited by His obedience (cf. 2 Cor. 5:21). It’s for that reason that the Law of Moses was never intended to be a means of justification. But that’s not to say that Mosaic Law was inherently bad. On the contrary, the Law is good—if one uses it lawfully (cf. 1 Tim. 1:8).
As fathers, we are called to lean on Him, learn from Him, and love like Him, so that our children might catch a small but meaningful glimpse of the Father we all need.
We don’t merely want our children to behave well. We don’t simply want them to memorize Bible verses, learn the right answers, or become respectable members of the church. We want them to know Christ.
