That's real prayer-power, most of us are happy if through our prayers we can take the dog for a walk without getting soaked. Link between the power of our prayers and the rightness of our lives before God. As we pray we bring not just our words but our whole selves, and that includes the goodness of our lives. God wants the sacrifice offered to him of holy people, lives given over to him. Unforgiven sin hangs like a dark cloud over us when we pray.
Real prayer has to start with real repentance.
What we need - forgiven people and a healed land. We have to pray for it, plead with God to forgive and to heal our nation, bring it back to him. As we pray for our city, our nation, God will hear us when we come as his people, humbly to pray, to seek God with pure hearts.
