The main problem nowadays is that people don't know who God is, and to make matters worse, they compare HIM with other gods. Maybe that is why some Christian chose to refer to him as YAHWEH. That brings me to say that the root of our problem today is the misunderstanding of who God actually is.
We should be less concerned about searching for who we are and searching for who God is; with this in mind, we will endeavour to focus on God's greatness and why He is so great that no one can compare. I have listed below twelve reasons why how great our God is matchless:
Unsearchable
Psalm 145:3 reads that God's greatness is unsearchable, that no one can fathom it. The greatness of God is incomprehensible. Infinite God cannot be understood by a finite people that we are. His greatness can't be put in a comprehensible expression. God has only given us the knowledge of what He wants us to know. We can spend our entire lives without getting to grasp the knowledge of God (Deuteronomy 29:29).
Holy
God is holy. His Holiness can't be compared to any other (1 Samuel 2:2). He does not have any sin, and even His name is Holy and eternal.
He has no Beginning
No one created God, He has no beginning, and no end, and He created all things; in fact, He created beginning and thus called the Alpha and the Omega, which is coined from the Greek alphabet.
Self-sufficient
God is self-sufficient God. He has no need of any kind. ….If I were hungry, I would not tell you, for the world is mine, and all that is in it (psalm50:10). God does not need us to guarantee His existence even despise our pride. He only wants us to be grateful for what we have received.
Changeless
Malachi 3:6 reads For I, the Lord, do not change. He is the same yesterday, today, and forever, unlike our ever.
He is before Time
Time's concept has always confused man, and we still want to put a beginning and timing to things, but God is God over Time. He exists outside of our time limitations. He is our everlasting Father.
Omniscience (knows everything)
He knows the end from the beginning. Great is our Lord, and abundant in power; his understanding is beyond measure (Psalm 147:5). Nothing can be hidden from God. He knows all.
Custodian of wisdom
"If you need wisdom, ask our generous God, and he will give it to you. He will not rebuke you for asking." –James 1:5. Only God has all the wisdom we need, and we only need to ask Him and His ways are not our ways.
Incorruptible God
God is faithful. He can always be trusted that He will not let us down; we can be sure that He will be there for us. God is greater than the highs and lows and He is dependable. Know therefore that the Lord your God is God; he is the faithful God, keeping his covenant of Love to a thousand generations of those who love him and keep his commandments (Deuteronomy 7:9).
God is good all the Time
God is everything that is good in the world. There countless passages in the bible, referring to the goodness of God. How many times have we had people said that something miraculously just turned at their lowest times. (James 1:17) says Every good and perfect gift is from above, coming down from the Father of the heavenly lights, who does not change like shifting shadows. God is the source of all. Nothing is created without His knowledge.
Omnipotent God (great in power)
Man and our limited power and resources are just impossible, but there is no impossibility in our great God. (Luke 1:37) reads, For nothing will be impossible with God.
Salvation
Salvation is found in no one else (Acts 4:12). God's Love has given us salvation despite our rebellion towards him. (1 John 5:11-12) says And this is the testimony: God has given us eternal life, and this life is in his Son. Whoever has the Son has life; whoever does not have the Son of God does not have life. God loves us and great in Love that He gave us His Son.
Great is the Lord and greatly to be praised, Our God is greater, and His greatness is unfathomable.
God bless you for reading and continue to stay with God, the everlasting Father.
