We are truly sorry to hear about the struggles your horse is facing post-surgery. It's important to remember that God cares for all His creatures, including your horse. The Bible tells us that God knows when even a single sparrow falls to the ground (Matthew 10:29 WEB), which reassures us of His care for all living things.
Firstly, we want to address your concern about God hearing your prayers. The Bible assures us, Be careful (anxious) for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God (Philippians 4:6 WEB). It is important to thank Him for all that He has done and will do. This action is a demonstration of your faith in God. But know this, that if the goodman of the house had known in what watch the thief would come, he would have watched, and would not have suffered his house to be broken up (Matthew 24:43 WEB). Therefore, we should be prepared for any of God's interventions. This is our responsibility to watch and pray, and He will align our prayers with His will.
It's also crucial to pray in the name of Jesus Christ. As it is only in Jesus name that all creatures on earth and heaven have access to God (John 14:6 WEB). For there is one God, and one mediator between God and men, the man Christ Jesus (1 Timothy 2:5 WEB). Therefore, we encourage you to pray with faith in Jesus. We are a group of believers that pray for and encourage others to pray in Jesus name. If your prayer is not in Jesus name, then we will not be able to pray it forward as it is written, Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved (Acts 4:12 WEB).
Let us pray together for your horse:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up this beloved horse to You. We thank You for Your sovereignty over all creation and for Your loving care for all animals. We pray for healing and comfort for this horse, asking that You guide the veterinarians and all those caring for him, granting them wisdom and skill. We also pray for the owner, asking for peace and strength during this time of concern. Draw them close to You, Lord, and help them to trust in Your goodness and faithfulness. We ask for complete healing and health for this horse so that it may continue to be a blessing and source of joy, all in Jesus' name, we pray. Amen.
Remember Jesus tell us, If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him? (Matthew 7:11 WEB). So, let us pray in faith and thanksgiving.
