Anything that has to do with focusing on "self"--be it self-esteem, self-image, self-worth, self ad-nauseum is not biblical. Our focus is to be on Christ, not on self. Self is our problem. Jesus said to "Deny self"
Luke 9:23 And he said to them all, If any man will come after me, let him
deny himself, and take up his cross daily, and follow me.
Paul said in
2 Timothy 3:1-5:
2 Timothy 3:1 This know also, that in the last days perilous times shall come.
2 Timothy 3:2 For men shall be
lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy,
2 Timothy 3:3 Without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good,
2 Timothy 3:4 Traitors, heady, highminded, lovers of pleasures more than lovers of God;
2 Timothy 3:5 Having a form of godliness, but denying the power thereof: from such turn away.
Jesus gave us
two commandments (not three) in
Matthew 22:37-40:
Matthew 22:37 Jesus said unto him, Thou shalt
love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.
Matthew 22:38 This is the
first and great commandment.
Matthew 22:39 And the second is like unto it, Thou shalt
love thy neighbour as thyself.
Matthew 22:40 On these
two commandments hang all the law and the prophets.
We are to love God and love our neighbor as we (already) love self. Loving self is implied here...otherwise Jesus would have given us three commandments instead of two. The fact that we focus so much on self is indicative that we already "love self". We hate the circumstances in which we find ourselves, which is still focusing on self. Not one person hates themself:
Ephesians 5:29 For no man ever yet hated his own flesh; but nourisheth and cherisheth it, even as the Lord the church:
