To love and serve God
Only one thing we need: to love and serve our Lord. This is what we also learn from wise king Solomon in Ecclesiastes (12, 13): “Fear God and keep His commandments” because of this is what the whole man consists of, and this is why the man was created by God. And anything beyond this, is characterized by the same author, king Solomon (Ecclesiastes 1, 2), “vanity of vanities”.
