God knows the propensities of the human heart very well. He made us, after all, and in his sovereignty, He knows what’s best for us.
In Deuteronomy 17, He lays out some rules for Israel’s future kings. The rules He gave were designed to be preventative measures to protect their hearts. He knew the power and wealth of their position could go to their heads, so He gave some guidelines.
Deuteronomy 17:18 says the king was required to write out the Old Testament Law in a book and read it every day. It wasn’t enough for him to own a copy of the Law on a scroll or even just to read it now and again. God said he needed to write it and read it “in all the days of his life.” Here is God’s reasoning:
“…that he may learn to fear the Lord his God…”
“…that his heart may not be lifted up above his brothers…”
“…that he may not turn aside from the commandment…”
“…that he may continue long in his kingdom, he and his children, in Israel.”
Deuteronomy 17:19-20 ESV
Writing it and reading it were protective, preventative measures.
Royalty or not, we have the same propensity for sin and pride as a king. The same guidelines God gave for the kings can have the same preventative and protective measures for our hearts.
Too many Christians are starving themselves spiritually as they wait for their pastors to feed them a meal on Sundays. Imagine how our lives would change if we read God’s Word and maybe even wrote about it every day! When we get into God’s Word, God’s Word gets into us, changing us and protecting our hearts.
