Integrity:
in-teg’-ri-ti (tom, tummah): The translation of tom, “simplicity,”
Genesis 20:5 Did he not himself say to me, ‘She is my sister’? And she herself said, ‘He is my brother.’ In the integrity of my heart and the innocence of my hands I have done this.”
It is interesting that the first use of the word integrity was said by Abimelech king of Gerar.

in·teg·ri·ty
noun
1. the quality of being honest and having strong moral principles; moral uprightness.
2. the state of being whole and undivided.
And Abimelech said to Abraham, “What did you see, that you did this thing?” Abraham said, “I did it because I thought, ‘There is no fear of God at all in this place, and they will kill me because of my wife.’ Besides, she is indeed my sister, the daughter of my father though not the daughter of my mother, and she became my wife.
The simple answer was that Sarah was his sister but fear on Abraham’s part kept him from revealing the whole truth. Abraham fell in love with his half sister and married her. Things in this world are never as simple as telling half truths.
The biblical definition of integrity isn’t just simplicity. It also means “soundness,” “completeness,” rendered also “upright,” “perfection.”
When we let fear interfere with soundness, completeness, uprightness and perfection, we have failed to trust God for our protection. I can say that because God said this; Then God said to him in the dream, “Yes, I know that you have done this in the integrity of your heart, and it was I who kept you from sinning against me. Therefore I did not let you touch her. Now then, return the man’s wife, for he is a prophet, so that he will pray for you, and you shall live. But if you do not return her, know that you shall surely die, you and all who are yours.”
God is faithful even when we are not. Abraham did not lie, he just let fear keep him from telling the whole truth. We are not perfect, not yet anyway. When we allow fear to keep us from being completely honest it allows those in the world to render a false assumption about our character.
Proverbs 3:5-6 Trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make straight your paths.
