True integrity is doing what is right when no one is looking.
Integrity includes being financially accountable and personally reliable.
John 1:47 When Jesus saw Nathanael approaching, he said of him, 'Here is a true Israelite, in whom there is nothing false.'
48 'How do you know me?' Nathanael asked.
Jesus answered, 'I saw you while you were still under the fig tree before Philip called you.'
Do you keep your integrity even in small matters?
If you are dishonest with little, you'll be dishonest with much – the principle is there.
Luke 16:10 'Whoever can be trusted with very little can also be trusted with much, and whoever is dishonest with very little will also be dishonest with much. 11 So if you have not been trustworthy in handling worldly wealth, who will trust you with true riches?'
