Pray that your husband will cultivate strong integrity, and not compromise his convictions. Pray that his testimony will be genuine, that he will be honest in his business dealings, and will never do anything that he needs to hide from others.
Proverbs 20:7: The righteous who walks in his integrity -- blessed are his children after him!
1 Timothy 1:5: The aim of our charge is love that issues from a pure heart and a good conscience and a sincere faith.
1 Timothy 3:7: Moreover, he must be well thought of by outsiders, so that he may not fall into disgrace, into a snare of the devil.
Ephesians 6:10-12: Finally, be strong in the Lord and in the strength of his might. Put on the whole armor of God, that you may be able to stand against the schemes of the devil. For we do not wrestle against fles and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places.
