In chapter 2, Isaiah was given a gift to see the future.
2 In the last days, the Temple of the LORD in Jerusalem will become the most important place on earth. People from all over the world will go there to worship. 3 Many nations will come and say, “Come, let us go up to the mountain of the LORD, to the Temple of the God of Israel. There he will teach us his ways, so that we may obey him.” For in those days the LORD’s teaching and his word will go out from Jerusalem.4 The LORD will settle international disputes. All the nations will beat their swords into plowshares and their spears into pruning hooks. All wars will stop, and military training will come to an end.
It is our sin and disobedience that leads to war. Some day God will remove our sin and weapons will be converted into tools of peaceful means.
Until then, if we do not choose to follow Christ and obey Him, just like he warned the Jewish nation in the remainder of this chapter, the wrath of the Lord is what we have to look forward to.
The last verse of this chapter also caught my attention:
22 Stop putting your trust in mere humans. They are as frail as breath. How can they be of help to anyone?
Lord, I declare my allegience to You. Help me to act according to Your will and not my own. Help me always put the needs of others above my own. Help me to trust in You, not in those around me. You are mighty and Your love is extravagant.
