A healthy relationship with God is built on the internal changes He brings about through Christ.
Chastening is a mark of affection, not a sign of rejection.
In a world of constant change, God alone is the Rock upon which to build a life.
In Deuteronomy 11, God offers Israel a choice; either a life of productivity and enjoyment made possible by obedience to Him, or a life of difficulty and opposition made necessary by disobedience. The happiness Israel desires can only be theirs by being properly related to Him.
God's commandments not only reflect His holiness, they promote our happiness.
Mental confusion can be the product of divine discipline.
