2. The Father best expresses God’s omnipotence
The term omnipotent means all-powerful. The Father has all power, but has temporarily given that to the Son. The Son has been given the responsibility to defeat all of God’s enemies and when His mission is completed He will return that power back to the Father.

Matthew 6:13; 28:18; Revelation 19:6; 1 Corinthians 15:22-28; Ephesians 1:19–22

3. The Holy Ghost best expresses God’s Omnipresence
Omnipresence means that God is everywhere. There is no place you can go where God is not there.

1 Kings 8:27; Psalms 139:7–8; 2 Timothy 1:14

B. Just as He has three parts, everything in God’s whole creation has three components.
“For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse” (Romans 1:20).

The components of the universe are space, matter, and time. These are each further broken down into three parts.

1. Space is composed of length, width, and height

2. Matter is composed of solids, liquids, and gases

3. Time is composed of past, present, and future

III. The Trinity in the Old Testament
The doctrine of the Trinity was not revealed until the time of Christ. However, as is often the case with New Testament doctrines, it can be found in the Old Testament once it is read in the light of the New Testament teachings. Armed with this New Testament derived knowledge, we can now look back and see the fullest meaning of several Old Testament passages.

A. The Jewish religion was strongly monotheistic
Deuteronomy 6:4; 2 Kings 19:15; Isaiah 44:6, 8; Zechariah 14:9; Malachi 2:10

B. God occasionally referred to Himself in the plural form
Genesis 3:22; 11:5–8
