Exceeding joy
Our relationship with the Lord is our strength (i.e. the reason for our joy). But Jude writes about joy that is exceeding (even more abundant):Now unto Him that is able to keep you from falling, and to present you faultless before the presence of His glory with exceeding joy. To the only wise God our Saviour, be glory and majesty, dominion and power, both now and ever, Amen.
