Isaiah 65:24 Before they call, I will answer; and while they are still speaking, I will hear.
God desires that we Christians be concerned and burdened for a lost world. If we pray this kind of prayer, an era of peace may come to the world and wickedness may be turned back. "The effective, fervent prayer of a righteous man avails much" (James 5:16)
Salvation is free, but there is a price to pay in following Jesus.
