The new city of Jerusalem serves as a metaphor for each and every one of us.
Outside of ourselves, there is a world full of sin (similar to outside the city of Jerusalem), and it is through our belief and trust in Christ that we are able to combat the temptations around us.
When I was younger, I found myself amongst the “dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie” (Revelation 22:15).
It takes great strength and faith in God to turn to him in times of uncertainty and avoid the persuasions of sin.
In the Book of Revelation 22:13-21, we find that God repeats His promise that He is “Alpha and Omega, the beginning and the end, the first and the last” (Revelation 22:13).
These words are emphasized by appearing twice in the same passage. We should feel confident that God is all-powerful and that through Him, we can feel safe and free of temptation.
