God’s presence radiates joy, and His joy permeates into every aspect of our being. That’s what ‘fullness’ means! If we as His people are to reflect His image, then we too must radiate joy. Back to what Loraine said… The reason the worship team could express such complete joy was because they were constantly in God’s presence. It is in His divine presence that immeasurable joy can be found. Hence, when we come into God’s presence we become ‘joy-full’ (people full of joy)! And that kind of joy cannot be obtained anywhere else. Also, it’s only those who are allowed to come into His presence that can be effected by the divine joy being radiated. The unbeliever cannot experience this kind of joy.
