Let us learn from these words to beware of self-righteousness. Nothing so blinds the eyes of our souls to the beauty of the Gospel as the vain, delusive idea, that we are not so ignorant and wicked as some, and that we have got a character which will bear inspection. Happy is that man who has learned to feel that he is "wretched, and miserable, and poor, and blind, and naked." (Rev. 3:17.) To see that we are bad, is the first step towards being really good. To feel that we are ignorant is the first beginning of all saving knowledge.~ J.C. Ryle
Interestingly, Revelations 3:17 is just one line in a letter written to the church at Laodicea (Rev. 3:14-22) not to those outside the covenant community. These words are for us, the people of God, and we would do well to heed them.
Be happy. Take off your blinders and see yourself as you really are. Have grace with others. Know Jesus. Be happy.
