There is one eternally existing God who has three distinct persons: God the Father, God the Son, and God the Holy Spirit. God is the creator of all that exists, both visible and invisible, and is therefore worthy of all glory and praise. God is perfect in love, power, holiness, goodness, knowledge, wisdom, justice, and mercy. God is unchangeable and therefore is the same yesterday, today, and tomorrow.
What God does
We cannot describe God with certainty. But we can put into words what God does and how we experience God's action in our lives. God works in at least these seven ways:
God creates. In the beginning God created the universe, and the Creation is ongoing. From the whirling galaxies, to subatomic particles, to the unfathomable wonders of our own minds and bodies—we marvel at God's creative wisdom.
God sustains. God continues to be active in creation, holding all in "the everlasting arms." In particular, we affirm that God is involved in our human history—past, present, and future.
God loves. God loves all creation. In particular, God loves humankind, created in the divine image. This love is like that of a parent. We've followed Jesus in speaking of God as "our Father," while at times it seems that God nurtures us in a motherly way as well.
God suffers. Since God is present in creation, God is hurt when any aspect of creation is hurt. God especially suffers when people are injured. In all violence, abuse, injustice, prejudice, hunger, poverty, or illness, the living God is suffering in our midst.
God judges. All human behavior is measured by God's righteous standards—not only the behavior itself but also the motive or the intent. The Lord of life knows our sin—and judges it.
God redeems. Out of infinite love for each of us, God forgives our own self-destruction and renews us within. God is reconciling the individuals, groups, races, and nations that have been rent apart. God is redeeming all creation.
God reigns. God is the Lord of all creation and of all history. Though it may oftentimes seem that the "principalities and powers" of evil have the stronger hand, we affirm God's present and future reign.
When all is done, if we have difficulty in imagining who God is or in relating to God, there's a simple solution: Remember Jesus—for in the New Testament picture of Jesus, we see God.
