There is an advocate and intercessor always waiting to present the prayers of those who come to God through him. The advocate is Jesus.
The bank note without a signature at the bottom is nothing but a worthless piece of paper. The stroke of a pen confers on it all its value. The prayer of a poor child of Adam is a feeble thing in itself, but once endorsed by the hand of the Lord Jesus it availeth much.
