What do you say about yourself?
Jn. 1:22 Then they said to him (John the Baptist), "Who are you, that we may give an answer to those who sent us? What do you say about yourself?" NKJV
Who are you? What do you think of yourself? What do you tell others about yourself? This is commonly called self esteem.
When John was asked, are you the Christ? He said no. Are you Elijah? No. Are you the Prophet? No. Does this mean John was suffering from low self esteem? No.
John knew who he was and what God had called him to do. He was a witness for Jesus, and a good one. He was a Christian, and a good one. So, who are you? What do you say about yourself?
