Pray that your husband will love righteousness and hate wickedness, especially the evils of the culture.
Pray that he will recognize and avoid wickedness in his own life, and if necessary, take a clear, strong stand against evil.
Scripture to read and consider:
The prudent sees danger and hides himself, but the simple go on and suffer for it.
I do not ask that you take them out of the world, but that you keep them from the evil one.
1 Corinthians 10:12-13
Therefore let anyone who thinks that he stands take heed lest he fall. No temptation has overtaken you that is not common to man. God is faithful, and he will not let you be tempted beyond your ability, but with the temptation he will also provide the way of escape, that you may be able to endure it.
