Rejoice always! Pray constantly. Give thanks in everything, for this is God's will for you in Christ Jesus.

I Thessalonians 5:16-18 (HCSB)

Intercessory prayer involves taking on another's burden and carrying on their behalf to the feet of Jesus. We intercede for others without even knowing, those little or short prayers you pray for your family, the needy, the world is all intercessory prayers.
