When you read that title, I bet the voice in your head has a tone of hopelessness. But if you believe in the God of the Bible, it should not be so.
"Now to him who is able to do immeasurably more than all we ask or imagine, according to his power that is at work within us, to him be the glory in the church and in Christ Jesus throughout all generations, for ever and ever! Amen." Ephesians 3:20-21
If that is true: God is in this for his own glory and He can do way more than we could possibly ask or even imagine. That means our prayers are quite powerful, because God wants to righteously one-up our prayers.
All life comes from God and He is glorified in creating, sustaining, redeeming and preserving it.
Pray for the people of Japan, that God may be glorified by answering in profound and unimaginable ways.
