We are spending the summer studying the book of 1st John. In our “By This We Know” series, we are exploring all the ways that John reassured us in his letter that we can know we have eternal life through Jesus Christ. John’s first epistle blends a spectacular balance of both making us feel loved and calling us to live to a higher standard. In today’s sermon, we look at the prologue and conclusion of John’s letter to lay a foundation for the series and understand John’s purpose for writing. We discover that it is our fellowship with the church (universal and local) that reassures us of our eternity.
