The prophet Micah told the people of Israel to hear the word of the Lord in Micah 6
Micah instructed them to plead for themselves loudly to the mountains so that even the hills could hear their voice. The Lord had an indictment against his people, and would deal with them for their sins.
The Lord spoke and asked, "O my people, what have I done to you? How have I wearied you? Answer Me!"
The Lord had brought them from the land of Egypt and freed them from their slavery. God reminded them of the evil that Balak, king of Moab devised against them, and how the Lord dealt with Balaam.
God asked them, "What will I bring when I come before the Lord?" God asked how could they come before them with their offerings thinking that by giving these things to God they could continue in their evil ways. The Lord asked if they thought he would even be pleased with thousands of rams and ten thousand rivers of oil. Would He even be pleased if they offered their own firstborn for their transgressions?
God said that He had told them what is good. He told them what the Lord required of them: To walk justly before God. To show love and kindness. To walk humbly with God.
This is the reason Christ came, to fulfill the law and turn the hearts back to Divine Love. "For it is by grace you have been saved, through faith--and this not from yourselves, it is the gift of God" (Eph 2:8)
As Christians, we should ask ourselves: Do we think that we are His children just because we are going to church every Sunday morning? Do we think that because we make big promises to God or give large amounts of tithe offering that God will allow us to walk without Love? Have we left the basic principle of the Bible, Love? Are we doing the three things God asked: walk justly, show love and kindness, and walk humbly?
