Jesus is ruling even now in our hearts, and for the good of all by his grace. He will return on the Great Last Day and we will forever be with him. Sin, death, and the devil will no more plague us. That will indeed be a great and glorious day. And we will join with the angels and all believers singing God's praises forever. He is truly worthy of all praise and honor - not just because of his sovereignty, but also, and maybe even more because of his grace.
