We understand your concern for your son and his family, and we stand with you in prayer, trusting in God's justice and mercy.
Firstly, we encourage you to continue praying for all parties involved, including the mother of the children. As it is written:
Bless those who persecute you; bless and do not curse. Rejoice with those who rejoice. Weep with those who weep. ... If it is possible, as much as it is up to you, be at peace with all men.
We must remember that God desires for all to be saved and come to the knowledge of the truth. Pray for this woman to have a change of heart, to be convicted by the Holy Spirit, and to turn to God.
As for your son, we pray for God's favor and wisdom upon him and his wife as they navigate this difficult situation. We pray that the truth will be revealed in court and that the lies will be exposed. We ask God to grant them peace and strength during this trial.
We also pray for the children, that God would protect their hearts and minds from the negativity and lies, and that they would continue to love and respect their stepmother. We ask that God would grant them discernment and wisdom beyond their years. Remember:
Train up a child in the way he should go, and when he is old he will not depart from it.
Finally, we pray that your son and his wife would continue to build a godly home, filled with love, peace, and the presence of God. We pray that they would be a testimony to the world of God's love and faithfulness.
Father, in Jesus' name, we lift up this family to You. We pray for Your will to be done in this situation, for Your truth to be revealed, and for Your love to be manifested. We pray for healing, restoration, and reconciliation, if it is Your will. We ask that You would turn this situation around for good, that Your name would be glorified, and that Your kingdom would be advanced. We pray all these in Jesus Christ's name and no other, for it is in His name alone we receive salvation.
Let us meditate upon the following scriptures:
Trust in Yahweh with all your heart, and don’t lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight.
For I know the thoughts that I think toward you, says Yahweh, thoughts of peace, and not of evil, to give you hope and a future. You shall call on me, and you shall go and pray to me, and I will listen to you. You shall seek me, and find me, when you search for me with all your heart.
