It was far above the power of nature, and even contrary to its laws, that the aged Sarah should be honored with a son; and even so it is beyond all ordinary rules that I, a poor, helpless, undone sinner, should find grace to carry in my soul the indwelling Spirit of the Lord Jesus. I, who once despaired, as well I might, for my nature was as dry and withered and barren and accursed as a howling wilderness, even I have been made to bring forth fruit unto holiness. Well may my mouth be filled with joyous laughter, because of the singular, surprising grace that I have received from the Lord, for I have found Jesus, the promised seed, and He is mine forever. Today I will sing psalms of triumph to the Lord who has remembered my low estate, for "my heart exults in the LORD; my strength is exalted in the LORD. My mouth derides my enemies, because I rejoice in your salvation."1
My desire is that all those who hear of my great deliverance from hell and my most blessed visitation from heaven will laugh for joy with me. I want to surprise my family with my abundant peace; I want to delight my friends with my ever-increasing happiness; I want to edify the church with my grateful confessions, and even impress the world with the cheerfulness of my daily conversation.
Bunyan tells us that Mercy laughed in her sleep, and no wonder when she dreamed of Jesus; my joy should not be less than hers while Christ is the theme of my daily thoughts. The Lord Jesus is a deep sea of joy: My soul shall dive in and shall be swallowed up in the delights of His company. Sarah looked on Isaac and laughed without restraint, and all her friends laughed with her. And you, my soul, look on Jesus, and invite heaven and earth to unite in your unspeakable joy.
