That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life;(For the life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us;) That which we have seen and heard declare we unto you, that ye also may have fellowship (koineo- link) with us: and truly our fellowship is with the Father, and with his Son Jesus Christ. And these things write we unto you, that your joy may be full. ( I John 1:1-4)Our joy is full when we allow God's life in Christ to rest in our hearts. However sometimes we get sidetracked from the full view of what God has in store and it feels like we've wandered out on dark scary road in the middle of the night. Do we just keep walking or do we turn our direction back to the warmth and comfort of the light of home. It just takes a recognition that we have wandered into someplace where we shouldn't be. Sin is being somewhere where we shouldn't be in both doctrine and practice. (You have to have both because just walking around with the doctrine under your arm instead of in practice can keep you out on that dark road.)
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 (katharizo in Greek; cathartic in English meaning purging or purifying) us from all sin (a wandering off the mark).(I John 1:5-7)If we walk in light we have fellowship with each other, we don't have to make fellowship with one another. God is light, there is not one micron of injustice, unkindness, failure, fear, politics (just had to throw that in), untruth, meanness or any other form of darkness you can think of. The Word of God can be more than just a flashlight lighting our path. It can be a noonday sun surrounding us with goodness and that's good for the soul!
