What does it mean to worship God with a whole heart?

Worshiping God with a whole heart, as stated in Psalm 111, highlights the necessity of both resolve and preparation in our acts of worship. This means that our worship should not be half-hearted or superficial; rather, it should encompass our entire being, including our intellect, emotions, and volition. When we approach God in worship, we must do so with a sincere heart that recognizes His greatness and our dependence on Him. True worship demands us to reflect on who God is and all He has done for us, fully engaging ourselves in the process of worship, whether in private meditation or in communal gatherings.
