While the people cynically questioned God’s justice and longed for his intervention, in Malachi 2:17-3:5, God told them he would be coming in judgment after his messenger prepared the way. In the New Testament, we learn who that messenger was and what God did when he showed up, which was a shock to all.

When Israel reached Mount Sinai, God showed that he would provide all they needed.
Faith is the means by which we are saved, obey God, and forgive our brothers and sisters.
