"These things we write, so that our joy may be made complete."
1 John 1:4
John wanted to share the truth of Christ's life with others. His testimony would bring greater faith and joy to those who received it, and that in turn would complete the Apostle's own joy. When we have a relationship with the Lord, we find a joy that is not dependent upon happy circumstances. In fact, some of the greatest joy we encounter is when things are at their worst. There is something so unique, so amazing about this kind of joy that we can't keep it to ourselves. We have to share it with others. Upon hearing it, their faith is strengthened, resulting in more joy for them. Our own joy is then made complete. This fellowship of joy continues, as long as we are willing to testify.
