Q. 1. What is the chief and highest end of man?
A. Man's chief and highest end is to glorify God,[1] and fully to enjoy him forever.[2]

[1]Romans 11:36. For of him, and through him, and to him, are all things: to whom be glory for ever. Amen. 1 Corinthians 10:31. Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God.
[2] Psalm 73:24-28. Thou shalt guide me with thy counsel, and afterward receive me to glory. Whom have I in heaven but thee? and there is none upon earth that I desire beside thee. My flesh and my heart faileth: but God is the strength of my heart, and my portion for ever. For, lo, they that are far from thee shall perish: thou hast destroyed all them that go a whoring from thee. But it is good for me to draw near to God: I have put my trust in the Lord GOD, that I may declare all thy works.
John 17:21-23. That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me. And the glory which thou gavest me I have given them; that they may be one, even as we are one: I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.
