““Be strong and courageous. Do not fear or be dismayed because of the king of Assyria nor because of all the multitude that is with him; for the one with us is greater than the one with him. With him is only an arm of flesh, but with us is Yahweh our God to help us and to fight our battles.” And the people were sustained by the words of Hezekiah king of Judah.”2 Chronicles 32:7-8 LSB https://bible.com/bible/3345/2ch.32.7-8.LSB
Hezekiah’s example in this passage is what it means to encourage one another to refresh the hearts of the saints. What did he do? He reminded his people, in the face of overwhelming circumstances, what God was capable of doing and how His presence was greater than the problem of their circumstances. Being right with God by loving Him first and most and obeying everything Jesus has commanded places us under the careful watch of His loving eye. God takes delight in delivering His people, showing Himself strong among us. This happens when we turn to Him in tough times and not to our own devices or the ability of others. Those who encourage, those who help the suffering, help people stay focused on God as the solution to their problem, not something else. It is the Lord we are to seek, the Lord to Whom we pray, the Lord to Whom we cry for help and mercy, and the Lord Who will deliver us. The Barnabas man, the one who encourages people, is the one who helps people see their God as bigger than their circumstances so that they can trust in Him.
