What does 'sanctify the Lord God in your hearts' mean?

To sanctify the Lord God in our hearts involves an intentional posture of reverence and surrender towards God. It signifies making God the priority of our lives and acknowledging His holiness in our daily conduct. This internal commitment manifests externally as we are empowered by the Holy Spirit to live in a way that honors Him. By doing so, believers cultivate a deeper relationship with Him, which naturally flows into their interactions with others, especially in facing trials or suffering. It is a call to make our devotion to God evident in how we navigate life’s challenges.
