" True happiness is always self-forgetful: it loses itself in the object of its joy. As the joy of the Holy Ghost fills us, and we rejoice in God the Holy One, through our Lord Jesus Christ. [. . .]

Love and joy ever keep company. Love, denying and forgetting itself for the brethren and the lost, living in them, finds the joy of God. ‘The kingdom of God is joy in the Holy Ghost. "

― Andrew Murray , Holy in Christ Thoughts on the Calling of God's Children to be Holy as He is Holy
