Words are wholly inadequate to describe God. In addition, we can only know those things of God that, in His grace, He has chosen to reveal (“Revealed Truth”). More will no doubt be revealed when the Believer meets Jesus face to face.

In the meantime, here is a jumping off point.

God is the Creator of Heaven and Earth. He exists eternally as three persons: the Father, the Son (Jesus Christ), and Holy Spirit (together “the Trinity”). God is eternal, infinite, and sovereign. He is omniscient, omnipresent, omnipotent, and unchanging. He is holy, just, and righteous. God is love, grace, mercy, and goodness.

As Immanuel (God with us), Jesus was fully God and fully man. He was born to a virgin, lived a sinless life, had a ministry of miracles, died an atoning death on the cross, was resurrected, and ascended to the right hand of God the Father as our High Priest and Advocate. His return to Earth in power and glory is imminent.

Jesus’s life and ministry is God’s ultimate expression of himself and the personification of His will and
message to humanity. The Bible, the inspired Word of God, is the written form of that message. Jesus is the living, embodied Word (from the Greek, logos, meaning word or reason), and the Bible is the inspired written testimony to Him.

The Holy Spirit, indwells and enables the Christian helping them to live a godly life. He regenerates sinners and indwells believers. He is the seal by whom God the Father guarantees the salvation of believers unto the day of redemption. And He is the Divine Teacher who illumines believers’ hearts and minds as they study the Word of God.

The following additional information is adapted from an @gotquestions post entitled “Who Is God?” We have removed the Scripture references as they make the piece difficult to read and assimilate. The original post with the Scripture references can be seen here.

The Fact Of God
The Bible never attempts to prove the existence of God. It assumes His existence from the very beginning. The fact of God’s existence is so conspicuous, both through creation and through man’s conscience, that the Bible calls the atheist a fool. The Bible revels the nature, character, and work of God.

The Definition Of God
Thinking correctly about God is of utmost importance. A false idea about God can lead to the sin of idolatry. In Psalm 50:21, God reproves the wicked man with this accusation: “You thought I was altogether like you.” To start with, a good summary definition of God is “the Supreme Being; the Creator and Ruler of all that is; the Self-existent One who is perfect in power, goodness and wisdom.”

The Nature Of God
We know certain things to be true of God for one reason: in His mercy He has condescended to reveal some of His qualities to us. God is spirit, by nature intangible. God is One, but He exists as three Persons, God the Father, God the Son, and God the Holy Spirit. God is infinite, incomparable, and unchanging. God exists everywhere, knows everything, and has all power and authority.

The Character Of God
Here are some of God’s characteristics as revealed in the Bible: God is just, loving, truthful, and holy. God shows compassion, mercy, and grace. God judges sin but also offers forgiveness.

The Works Of God
We cannot understand God apart from His works, because what God does flows from who He is. Here is an abbreviated list of God’s works, past, present, and future: God created the world; He actively sustains the world; He is executing His eternal plan which involves the redemption of man from the curse of sin and death; He draws people to Christ; He disciplines His children; and He will judge the world.

A Relationship With God
The Son of God became the Son of Man (the incarnation of Jesus Christ) and is therefore the bridge between God and man. It is only through the Son that we can have forgiveness of sins, reconciliation with God, and eternal salvation. In Jesus Christ “all the fullness of the Deity lives in bodily form.” So, to really know who God is, all we have to do is look at Jesus.
