Thank you, Father God, for the sanctity of Christian marriage. In the Christ Yeshua's name, heavenly Father, convict this other-woman not to interfere in this couple's relationship. Grant conviction to her heart, because you have commanded her not to commit adultery.
Righteous Father, keep this husband and wife from ever being entangled with adultery or any other marital infidelity.
I pray that You will heal this couple's hearts and protect them, and protect their children, from malice intentions of others. Pour out Your love upon this husband and wife, and their children, giving them each a strong sense of commitment to each other, to their children, and to You. Amen
