In the previous posts on joy we looked at the Triune God as the true source of all joy and the biblical theme of joy in God’s presence. The New Testament pushes us one more step in understanding the dynamic of joy. Take a look at 1 John 1:3-4.
That which we have seen and heard we proclaim also to you, so that you too may have fellowship with us; and indeed our fellowship is with the Father and with his Son Jesus Christ. And we are writing these things so that our joy may be complete.
The good news that John proclaims is the message that links people to the Triune God. Gospel trust leads to Triune fellowship. This is where joy is made complete. Of note, it is fellowship with the Father and the Son that completes our joy.
In other words, joy is experienced as we know relationship with the distinct persons of the Trinity. The ultimate gift of the gospel is God himself—he gives the fulness of himself to us. That means the Father gives himself, the Son gives himself, the Spirit gives himself.
When acted upon by God we experience the grace of the entire Trinity. The relationship that God creates through our redemption is marked by communion with the entire Trinity. As we engage all three persons, joy awaits.
