Malachi 4:1-6 are Jehovah's last words to His people before the four hundred years of divine silence.
When God is silent, strangely silent and there is a seemingly endless void between you and Him, turn to Him in faith and cling to His promises.
"I wait for Jehovah, my soul doth wait, and in his word do I hope" (Psalm 130: 4; ASV).
