We Love God!

God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)

In the past, God had left sins unpunished. He could conceivably be accused of overlooking sin since He had not required punishment for it. Now, however, He has put forth Jesus. This proves that God is just (His wrath required the sacrifice) and that He is the justifier of those who have faith in Jesus (His love provided the sacrifice for them).

Hence that dread and amazement with which as Scripture uniformly relates, holy men were struck and overwhelmed whenever they beheld the presence of God. When we see those who previously stood firm and secure so quaking with terror, that the fear of death takes hold of them, nay, they are, in a manner, swallowed up and annihilated, the inference to be drawn is that men are never duly touched and impressed with a conviction of their insignificance, until they have contrasted themselves with the majesty of God.
John Calvin
