Thank you for bringing this concern to us. We will be glad to intercede for your neighbor's father. God cares about each one of us and even the health of an individual. It is very important that they know Jesus since it is only through Jesus that we have access to God. God hears and answers only those who come to him through Jesus.
It is only through Jesus we are saved, and we pray for this man.
And in no other is there salvation, for neither is there any other name under heaven, given among men, in which we must be saved Acts 4:12 WEB
So, we will pray for healing but most importantly for salvation if he doesn't know Jesus.
Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me. John 14:6 WEB
Therefore, confess your sins to one another, and pray for one another, that you may be healed. The insistent prayer of a righteous person is powerfully effective. James 5:16 WEB
Is anyone among you suffering? Let him pray. Is anyone cheerful? Let him sing praises. Is anyone among you sick? Let him call for the elders of the assembly, and let them pray over him, anointing him with oil in the name of the Lord, and the prayer of faith will heal him who is sick, and the Lord will raise him up. If he has committed sins, he will be forgiven. James 5:13-15 WEB
Let us pray.
Dear Heavenly Father,
We come before You today, lifting up the father of our neighbor who is quite sick. We ask, Lord, that You would have mercy on him and grant him healing. We pray that Your healing power would flow through his body, restoring him to full health.
More importantly, Lord, we pray for his salvation. If he does not know Jesus, we ask that You would reveal Yourself to him in a powerful way. Send people into his life to share the gospel and draw him to You. We pray he confesses his sins and accepts Jesus Christ as his one and only savior. Holy Spirit, work in his heart and bring him into a saving relationship with Jesus Christ right now.
Thank You, Jesus, for the forgiveness of sin, and the healing that is received for those who believe in You. We thank You that he is being saved right now with our prayers if he is not already saved.
We ask this in the name of Jesus Christ, our Lord, and Savior. Amen.
