From a sermon by Saint Augustine, bishop
The heart of the just man will rejoice in the Lord

The just man will rejoice in the Lord and put his hope in him; the hearts of all good men will be filled with joy. We must surely have sung these words with our hearts as well as with our voices. Indeed, the tongue of the Christian expresses his deepest feelings when it addresses such words to God. The just man will rejoice, not in the world, but in the Lord. Light has dawned for the just, Scripture says in another place, and joy for the upright of heart. Were you wondering what reason he has for joy? Here you are told: The just man will rejoice in the Lord. Another text runs: Delight in the Lord, and he will give you your heart’s desires.

What are we instructed to do then, and what are we enabled to do? To rejoice in the Lord. But who can rejoice in something he does not see? Am I suggesting that we see the Lord then? No, but we have been promised that we shall see him. Now, as long as we are in the body, we walk by faith, for we are absent from the Lord. We walk by faith, and not by sight. When will it be by sight? Beloved, says John, we are now the sons of God; what we shall be has not yet been revealed, but we know that when it is revealed we shall be like him, because we shall see him as he is. When this prophecy is fulfilled, then it will be by sight.

That will be the great joy, the supreme joy, joy in all its fullness. Then we shall no longer drink the milk of hope, but we shall feed on the reality itself. Nevertheless, even now, before that vision comes to us, or before we come to that vision, let us rejoice in the Lord; for it is no small reason for rejoicing to have a hope that will some day be fulfilled.

Therefore, since the hope we now have inspires love, the just man rejoices, Scripture says, in the Lord; but because he does not yet see, it immediately goes on to say, and hopes in him.

Yet already we have the first fruits of the Spirit, and have we not also other reasons for rejoicing? For we are drawing near to the one we love, and not only are we drawing near – we even have some slight feeling and taste of the banquet we shall one day eagerly eat and drink.

But how can we rejoice in the Lord if he is far from us? Pray God he may not be far. If he is, that is your doing. Love, and he will draw near; love, and he will dwell within you. The Lord is at hand; have no anxiety. Are you puzzled to know how it is that he will be with you if you love? God is love.

“What do you mean by love?” you will ask me. It is that which enables us to be loving. What do we love? A good that words cannot describe, a good that is for ever giving, a good that is the Creator of all good. Delight in him from whom you have received everything that delights you. But in that I do not include sin, for sin is the one thing that you do not receive from him. With that one exception, everything you have comes from him.
