Dominic Jackson opens our series on 1 John by reflecting on how the Christian faith begins not with ideas or inspiration, but with a person—Jesus Christ—whom John and the apostles heard, saw, and touched. The letter begins with eyewitness testimony and a call to deeper fellowship: not just with God, but with one another. In a world where many are uncertain what is true or who can be trusted, John grounds faith in what is real, embodied, and eternal. The invitation is not to escape into private spirituality, but to enter a shared life animated by joy, honesty, and love. This is how we walk in the light—not alone, but together in the truth.
