When Micah prophesies that the Lord will come in all his power and might, he tells the people the reason for his coming. It is because of the sins of the people. As much as God warned the people of what was to come, they still chose to ignore him. As a result of this, they would reap what they had sown.
Paul wrote about a similar thing when he wrote to the church in Rome:
"For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord." - Romans 6:23
The greatest gift we are given this Advent is the gift of Jesus, God's precious son. God's knows of each one of our sins, but he extends his love to all who would believe and receive him.
Living in Grace
