When we are ashamed of our pleading for ourselves
He ever lives and abides a Priest continually. His continuance in the Priestly office should comfort us under all our heart-breakings, short-comings, and deadness in prayer and praise; his blood will be heard for us — when we are ashamed of our pleading for ourselves.
My soul, keep your eye on Jesus whenever you approach the divine Majesty; he is your Priest, his blood is your plea, and his name and office are all your confidence.
Poor sinner, are you distressed in your approaches to God on account of your unworthiness, barrenness, wanderings, and coldness? Remember, Jesus stands between you and the divine throne! He appears as a Priest for you — let this encourage you. He looks upon Christ, and is well pleased with all who approach him through Jesus. He loves to hear us plead our Savior’s name — and to see us trust on his atoning blood.
