Greetings,
if it were my brother traveling as your brother is, i would be concerned, also, and would ask in prayer that he be safe, as such a journey can be dangerous.
Also, as you are our Sister in Christ, your brother becomes also our brother.
Have been praying and will continue.
Thank you for entrusting us to pray for your brother in this way and for you, that you may have God's comfort regarding your brother and God's care for Him
Bless you ....><>
