In the name of the Father and of the +Son and of the Holy Spirit. Amen.
It is of use to you that Jesus went away. A great and holy use. Beneficial in every way. For now that our Lord is heaven at the right hand of the Father ruling all things on His behalf He has sent His Holy Spirit into the earth, specifically into the hearts of mankind through the preaching of His Word and the distribution of His Sacraments. Why is this Helper of such great use to you? Because “I cannot by my own reason or strength believe in Jesus Christ, my Lord, or come to Him; but the Holy Spirit has called me by the Gospel, enlightened me with His gifts, sanctified and kept me in the true faith.” (Luther's Small Catechism: Explanation to the Third Article of the Creed)
