The proper response to God's whole counsel is first to find one's need-love met in sharing with Him, through the Holy Spirit (the joy experienced by God), and then second to make that joy full by talking about it with other people… We will also want to "double our joy" by discussing with fellow Christians the implications of God's great purpose for the world. So even though there will be no more evangelizing to do in (heaven), yet we Christians can continue to have the increased joy of talking about God's love with others.
