Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God…let us come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need. – Hebrews 4:14,16

If Jesus has gone into the glory, how successful must our prayers be. You send a petition to court, and you hope for its success, for it is drawn up in proper style, and it has been countersigned by an influential person; but when the person who has backed your plea for you is himself at court, to take the petition and present it there, you feel safer still. To-day our prayers do not only receive our Savior’s imprimatur, but they are presented by His own hand, as His own requests. No prayer which Jesus urges can ever be dismissed unheard for that case is safe for which He is advocate.

“Look up, my soul, with cheerful eye
See where the great Redeemer stands;
The glorious Advocate on high,
With precious incense in His hands.

He sweetens every humble groan,
He recommends each broken prayer;
Recline thy hope on Him alone,
Whose power and love forbid despair.”

~ C.H. Spurgeon
