2 In the last days the mountain of the Lord’s temple will be established as the highest of the mountains; it will be exalted above the hills, and all nations will stream to it. 3 Many peoples will come and say, “Come, let us go up to the mountain of the Lord, to the temple of the God of Jacob. He will teach us his ways, so that we may walk in his paths.” The law will go out from Zion, the word of the Lord from Jerusalem. 4 He will judge between the nations and will settle disputes for many peoples. They will beat their swords into plowshares and their spears into pruning hooks. Nation will not take up sword against nation, nor will they train for war anymore. 5 Come, descendants of Jacob, let us walk in the light of the Lord. (Isaiah 2:2-5)
When’s the last time you had a “wake-up call”? Most of us have these “wake-up” calls when we are met with our own mortality. It usually comes at an unexpected time when the last thought of your mind is that I might not be here tomorrow when “BAM!” something happens that makes you realize that life isn’t as long as you thought. We just never know when we will meet our Lord.
This time before Christmas is called the season of Advent and it is supposed to serve as a kind of “wake-up” call for believers. As we look forward to celebrating our Savior’s first coming at Christmas we are also called to lift our eyes to heaven and prepare ourselves for his second coming. Just as he came once, we can be sure that He is coming again. We are called to clothe ourselves in the righteous robes of Christ instead of our sinful acts and to live in such a way that we are always ready for Jesus to return. Isaiah encourages us saying, “Let us walk in the light of the Lord!”
We can walk in the light of the Lord because God has lifted up his salvation for all to see. It is chief among the mountains. Other “mountains” – religions, philosophies, and ways of life – are not even foothills compared to God’s salvation. All false religions share the same idea – basically, it’s up to you to save yourself. They may make sense to our human way of thinking, but that’s only because they are manmade. God’s revelation in Jesus is unique. There’s nothing like it in the world. He freely offers salvation, not on the basis of our effort or performance, but on the basis of his innocent blood which he offered on the cross.
But what happens if we choose that walking in the light of the Lord isn’t what we want? Can we still be saved if we decide to “do our own thing” or “believe whatever we want”? The answer is, “No!”
Isaiah says, “Let us walk in the light of the Lord!” When Jesus talked about the end of the world he spoke a hard message, “Wake up! The end will come when you don’t expect it. The time to repent (the time to follow Christ) is now!”
This is a wake-up call that each one of us needs to hear, because each one of us struggles with our sinful nature. God threatens us with his law so that we will turn from our sins and cling to Jesus alone, so that we will remain a part of those who are flocking to the mountain of the Lord.
Why though, would we want to follow Christ? Why should we be willing to put aside our desires, this world, and everything else, to walk in the light of the Lord?
It is because of what Christ came to give us: heaven. He came to free us from this sinful world, our own sins, and hell itself. Following Christ may not be popular to many but no one can give us what Christ won for us: eternal life with him in heaven.
When we consider what we have in Christ, we will be more than willing to follow him and to walk in his light always.
Happy for the salvation Christ won for me, just like you!
