Why is obedience to God important in a Christian's life?

Obedience to God is of paramount importance as it is the tangible expression of our love for Him. In John 14:15, Jesus calls us to keep His commandments as an act of love. This obedience is not only a response to God's love for us but also aligns us with His divine purpose, leading to our growth in faith and sanctification. By obeying Him, we also demonstrate our trust in His character and goodness, which brings about a deeper relationship with Him and fulfillment of His promises in our lives.
