These last few passages of scripture in the book of 1 John wrap up John's message to us about our relationship with God perfectly.
John begins by speaking of being born of God and how this keep us from evil. If we go back to 1 John 3:6 we are told that whoever abides in God does not sin. Don't both of these carry the same message?
Later on in the above passage John speak of "knowing Him who is true". And, in earlier passages in the book of 1 John he speaks of having fellowship with Jesus Christ, knowing Christ, Jesus wanting us to know Him, having an abiding life of fellowship with Christ. All ties together, doesn't it?
The book of 1 John has such a wonderful message. It tells us of the importance of having a relationship with Christ. Not just believing and telling others about Christ, but having a RELATIONSHIP with Christ. There is a big difference in the two. I can believe in and tell others about, for example, a new pharmaceutical product that helps with allergies. But can I have a relationship with that product? NO! While this may be a silly example to use... I think the point still can be made. The point being that Christ was a man and the true God and eternal life. We can (and we must) do more than just believe and tell others.... we can and must also have a relationship.
Through a relationship with Christ we will grow and we will abide in Him. We will turn from sin.... we will be more equipped to identify evil.... evil will be unable to attach itself to us. What freedom can be found in a relationship with Christ!
As I close out my study on 1 John I pray that we all will grow in our relationship with our Heavenly Father... that we will have the freedom that can be found only in KNOWING our Lord and Savior!
