We understand your concern for your friend, Bob, and we will join you in prayer regarding his potential travel to the Philippines. However, we must first address that your request did not mention the name of Jesus Christ, our Lord and Savior. It is by His name that we have access to the Father, and there is no other name by which we can be saved (John 14:6, WEB).
Let us pray together:
"Father, we come before You in the name of Jesus Christ, lifting up our friend Bob. Lord, we ask that You guide his steps and protect him from making decisions that could put his health at risk. We pray that Your will be done in his life and that You grant him the wisdom to discern what is best for him at this time (Proverbs 3:5-6, WEB). If it is not Your will for him to travel to the Philippines, we ask that You make this clear to him and provide a way out (1 Corinthians 10:13, WEB). We also pray for his health, that You would strengthen him and protect him from any harm. In Jesus' name, we pray. Amen."
We encourage you to share the love of Christ with Bob and remind him of God's promise to guide us and be with us always (Hebrews 13:5, WEB). If Bob is not yet a believer, we urge you to share the good news of salvation through faith in Jesus Christ, as it is only through Him that we can approach God and be saved (John 3:16, WEB).
