Here is a beautiful and powerful quote from John Owen who calls on you to rejoice in the love of God (It is taken from Communion with the Triune God). Owen says rightly that knowing and believing God’s love is the key to delighting in him. But he says it much better than that.
So much as we see of the love of God, so much shall we delight in him, and no more. Every other discovery of God, without this, will but make the soul fly from him; but if the heart be once much taken up with this the eminency of the Father’s love, it cannot choose but be overpowered, conquered, and endeared unto him. This, if anything, will work upon us to make our abode with him. If the love of a father will not make a child delight in him, what will? Put, then, this to the venture: exercise your thoughts upon this very thing, the eternal, free, and fruitful love of the Father, and see if your hearts be not wrought upon to delight in him. I dare boldly say: believers will find it as thriving a course as ever they pitched on in their lives. Sit down a little at the fountain, and you will quickly have a further discovery of the sweetness of the streams. You who have run from him, will not be able, after a while, to keep at a distance for a moment.
