Hosea6:5 Therefore have I hewed them by the prophets; I have slain them by the words of my mouth: and thy judgments are as the light that goeth forth.6 For I desired mercy, and not sacrifice; and the knowledge of God more than burnt offerings.
Matthew 9:12 But when Jesus heard that, he said unto them, They that be whole need not a physician, but they that are sick.13 But go ye and learn what that meaneth, I will have mercy, and not sacrifice: for I am not come to call the righteous, but sinners to repentance.
Matthew 12:6 But I say to you that something greater than the temple is here. 7 But if you had known what this means, ‘I desire compassion, and not a sacrifice,’ you would not have condemned the innocent.
So Hosea says it once and Jesus quotes it twice once when He is being criticized for who He is hanging out with and once when His disciples are being criticized for their actions on the Sabbath.
One more Psalm 102:13 You will arise and have pity on Zion; it is the time to favor her; the appointed time has come. 14 For your servants hold her stones dear and have pity on her dust. God is moved to pity when He sees His servants having pity/compassion/mercy. I think He is working in us a knowledge, a deep knowledge of how much we need mercy, so that, we are then vessels of mercy to other people.
Romans 9:22 What if God, although willing to demonstrate His wrath and to make His power known, endured with much patience vessels of wrath prepared for destruction? 23 And He did so to make known the riches of His glory upon vessels of mercy, which He prepared beforehand for glory,
Suffering is tied to “our” glory, and mercy is tied to “His” glory.
Stuff worth thinking about.
