Ephesians 4:4-7 There is one body and one Spirit—just as you were called to the one hope that belongs to your call— one Lord, one faith, one baptism, one God and Father of all, who is over all and through all and in all. But grace was given to each one of us according to the measure of Christ’s gift.
So how does believing in the Trinity affect your life? How do you live differently because of the triune God? What part of believing that God is made of one substance but three persons makes this doctrine “Christian” and what does it mean for the church?
While many religions around the world focus on works and performance, Christianity stands out. We, as Christ followers, don’t give all of our focus to our performance, but the core of our belief is relationship. God is about relationships. In fact, the very first model of a perfect community is given in the Trinity. In the Bible we have Father, Son and Holy Spirit as an example for us of relationships.
There is no sin in God so He is not tainted by its effects. Among the Father, Son and Holy Spirit are truth, love, humility, peace, service, honor, and unity. There is no grumbling or complaining, no backstabbing, no gossip. Though all three persons of the Trinity are equally God, there are different roles for each. But we never see the Son disgruntled about carrying out the will of the Father, we never see the Holy Spirit resent bringing glory to the Son. Because within each person of the Trinity there is the others (all one God, all one essence), they work together in perfect harmony.
We can’t be perfect, so we can’t live in the unity and harmony of God, but we have an example set before us to mimic to the best of our ability. Not to gain perfection, but to carry on good relationships, both with other people and with God. God is about community, about selfless relationships and love.
