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.
The godly walk with integrity;
blessed are their children who follow them.
1 Timothy 1:5
The purpose of my instruction is that all believers would be filled with love that comes from a pure heart, a clear conscience, and genuine faith.
1 Timothy 3:7
Also, people outside the church must speak well of him so that he will not be disgraced and fall into the devil’s trap.
A final word: Be strong in the Lord and in his mighty power. Put on all of God’s armor so that you will be able to stand firm against all strategies of the devil. For we are not fighting against flesh-and-blood enemies, but against evil rulers and authorities of the unseen world, against mighty powers in this dark world, and against evil spirits in the heavenly places.
