In her sermon, Heather discusses encountering God through worship, which goes beyond music and into a lifestyle of surrender. She emphasizes the Word of God as our sword in life's challenges, as Jesus demonstrated in the wilderness. Worship, in its biblical definition of bowing down, requires surrender and sacrifice. It's a costly act of giving our affection to God, as in the greatest commandment of loving Him with all our heart, soul, and mind. This form of worship transforms us, leading to awe and wonder, and allowing for an intimate encounter with God. Heather cites King David's example of extravagant worship, involving not just our challenges but also our successes and joys. This worship, born from a genuine love and knowledge of God, is a response to His love and the sacrifice of Jesus, inviting us into a deeper relationship with God.
