Looking at ourselves with sober judgement demands a measure of integrity and honesty.  It would be wrong to read Paul’s words as condemning a positive self-image—he is clearly stating that we should not think more highly of ourselves than we ought, or overly inflating our self-image beyond an honest assessment of our strengths and weaknesses.  Dr Bloom describes a person with self-integrity as one who knows themselves with sober judgement, and when we are a child of God, that sober judgement should tell us that we are not junk—there is something about us that is good, and wholesome, and beneficial for not only ourselves but for others.  Obviously, these things are a gift from God, either placed inherently in us as a unique human creature, or poured upon us by the Spirit as we enter into life with Jesus as our Lord.  On the whole, self-integrity is knowing ourselves, our self-esteem and self-worth balanced in a sober understanding of who we are as God’s children, both good and bad.
