To worship in spirit is to be led by the living God and to know the joy that comes from fellowship with the Holy Spirit. Holy Spirit is like a refreshing drink of water, a cool breeze, the warmth of a fire. He can also be a torrent, a hurricane, and a wildfire. Our experience of worship can be alive when we worship in spirit. True worship must first be in spirit – led by the Spirit and involves our spirit, the in-most part of our being.
To worship in truth is to ground our life in God’s truth, in His eternal Word, the Bible. We cannot worship however we want and do whatever we feel like. To worship is to bow before God and to delightfully follow His orders. We get to do what God says and not follow after the sin that used to enslave us.
