We understand your concern for your neighbor Dennis and we join you in praying for his salvation. The Bible tells us that God desires for all people to be saved and to come to the knowledge of the truth (1 Timothy 2:3-4, WEB). It is only through Jesus Christ that we can be saved, as it is written, "In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace" (Ephesians 1:7, WEB).
Let us pray together:
"Heavenly Father, we come before you in the name of Jesus Christ, lifting up our neighbor Dennis to you. Lord, we ask that you soften his heart and open his eyes to the truth of the Gospel. Draw him to yourself, God, and grant him the gift of salvation through faith in Jesus Christ. We pray that Dennis would come to know the love and grace that is found only in you. In Jesus' name, we pray. Amen."
We encourage you to continue sharing the love of Christ with Dennis and to be a light in his life. Remember, God's Word does not return void (Isaiah 55:11, WEB), so keep praying and trusting that God is at work in Dennis' life. Be ready to share the hope that is within you with gentleness and respect (1 Peter 3:15, WEB).
