We are glad to join you in prayer for your siblings, Anonymous. Children are a blessing from God. However, we must remember that God's blessings come in many forms, and his ways are not our ways. Let's pray to God for God to fulfill the desires of their hearts.
As we are told in Psalm 37:4 WEB, Delight yourself also in Yahweh, and he will give you the desires of your heart.
Let's pray:
Dear Heavenly Father,
We come before you in the name of Jesus, lifting up the siblings of Anonymous. Father, you know the depths of their hearts and their desire for children. We ask that you bless them and that they are able to delight in you and to see you fulfilling the desires of their hearts according to your will. We pray that they will be encouraged and filled with God's will, and that they grow closer to Him. We ask for your blessings upon them and their marriages, that they may be fruitful in every way.
In Jesus' name, we pray and give thanks to God. Amen.
Anonymous, we also encourage you and your siblings to trust in God's timing and will. Remember that God is faithful and that he works all things together for the good of those who love him, for those who are called according to his purpose in Romans 8:28 WEB. Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God in Philippians 4:6 WEB. We know that God hears our prayers and that He knows what is best for us. Again, We ask this in Jesus name and that God will answer the prayer as He wishes.
