JESUS TAUGHT US that we are to "love one another as I have loved you." What was the greatest act of love that Jesus portrayed? He laid down His life as an intercessor. The greatest act of love you can do for a person is to be their intercessor in prayer.
One hand on God. One hand on man.
When you stand in the gap on behalf of someone, you are setting certain spiritual laws in motion on your behalf as well. You are operating in the law of love under the New Testament. God will bless you exceedingly abundantly above all you can ask, hope, dream or desire.
