What do we need to do to continue to follow the path to eternal life and not destruction?

There is only one path to eternal life. As Christians, we believe faith alone in Jesus’ work alone is the way to eternal life. We know that to be true from God’s Word, from history, and from personal and community experience. If you deviate from that path, which Jesus calls the narrow path, then you will not make it to heaven. Instead, you will end up in a place called Hell where God’s wrath is poured out on you. 

How do you stay on the path to eternal life and not destruction? How do you stay on the narrow way?
