Michael Reeves shows how the Trinity is the basis of the unity Christians share in the eighth of nine short videos.
Jesus prays to his Father in John 17, that all those who believe in him may be one, Father, as we are one. Now that’s extraordinary—he’s asking for believers to be united. Now, if God were not three persons united in their great love for each other, then that oneness would probably mean being all the same, and that’s exactly what you get to see in, for example, the cultures dominated by a single-person God like Allah. There, under Islam, different cultures are brought to be identical; people are all brought to be the same. With this God, different people are affirmed in their created differences, and can still come together in loving unity. Now at the heart, we’re talking about the church, but here is the hope for the world. With this God, male and female, black and white, introvert and extrovert can all come together, not to try to be the same, but to be united in love. This God is the hope for world peace.
