In this sermon, Malachi will highlight that Covenant Faithfulness of God is grounded in His very nature which is Immutable. Further, in this sermon attention will be given to show that for those who are in the Covenant of Grace with God they will experience the Christ as a Refining Fire in their life who will purify and cleanse them through the work of regeneration and sanctification. However, those who refuse the Christ will experience Him as a consuming fire in judgment.
