This then is the message which we have heard of Him and declare unto you, that God is Light, and in Him is no darkness at all. If we say that we have fellowship with Him, and walk in darkness, we lie, and do not the Truth: But if we walk in the Light, as He is in the Light, we have fellowship one with another and the Blood of Jesus Christ His Son cleanseth us from all sin. If we say that we have no sin, we deceive ourselves, and the Truth is not in us. If we confess our sins, He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. If we say that we have not sinned, we make Him a liar, and His Word is not in us. 1 John, Chapter 1, verses 5-10.
This reminds me of being lost in a cave with lots of different tunnels. If we know that God is the Light that we see at the end of the tunnel, we are relieved. If we move confidently toward that Light, we will be saved. The darkness is all types of worldly things like: greed, drugs, infidelity, gossip and a variety of other things that can lead us away from our focus on Jesus, who is our Light and Salvation.
Now, if we tell ourselves that the Light at the end of the tunnel is too far away and give up, we can lose our way by getting lost running down the wrong tunnels, trying to navigate the worldly temptations in darkness and lose our focus on God.
Salvation is ours if we look down the tunnel and see the path that God provides for us as He illuminates the way, if we’d only let Him.
Because this is an example of how I’ve applied this Bible passage to my life, it doesn't necessarily reflect the whole meaning of the passage.
