You and I can also use this weapon against our foe. Too many of us (me included) view prayer as solely an 'ask and thou shalt receive' tool and overlook its usefulness as a weapon against our enemy(ies). Prayer isn't a weapon like a sword, it's more of a weapon like a battle horn - we're calling for backup!
When Christ was afflicted, saddened or was weary He would go into a private place and pray - not eat, not drink, not play video games, not watch TV, but talk to the Father and release all of His concerns.
I have really felt the pull into intercessory prayer (prayer for others); especially for the people I love that have been pulled into addictions or mindsets that I have seen and/or struggled with. I'll pray almost to the point of tears for those losing the battle with alocholism, pornography, pessimism and sexual sin. Lately I've felt called to pray for marriages, as I said in a previous blog Satan hates marriages and wants them all to come apart (or never start) - so I plead on others' behalf for marriages to be strengthened.
1 John 5:14 - "This is the confidence we have in approaching God: that if we ask anything according to his will, he hears us."
