God is the ultimate Being in existence, perfect in power, love, and character. Since God wanted to share His love with others, He created the angels and human beings—spiritual creatures who can related to Him. Because God is love, He wants us to love Him and love other people (Matthew 22:37-40). God came to earth in human form as Jesus of Nazareth to teach us about Himself and to provide the ultimate sacrifice for our sins, so that those who believe can have fellowship with Him. The Bible encourages all people to turn from their selfishness to become lovers of God, to fulfill God's perfect law of love.
According to Christianity, God is the self-existent One, having no need of being created, since He has existed forever and is the cause of all things, including the dimension of time, to which He is not subject (see If God Created Everything, Who Created God?). Likewise, God is not subject to the physical creation, but is spiritual in nature, residing in the spiritual dimensions of heaven. God's power over the physical creation is absolute, such that He can manipulate matter, energy, space, and time at will. For this reason, God is said to be all powerful—able to accomplish any possible task He wills to do.
Along with being all powerful, God is also all knowing—having knowledge of all things that are possible to be known, including the entire history of the universe—past, present, and future. Because God is all powerful (omnipotent) and all knowing (omniscient), He is also able to be present at all places at all times (omnipresent). God is also all loving—according to the Bible, "God is love" (1 John 4:16). The love of God prompted Him to create human beings in His image, in order to share His love with us. The Christian scriptures say that we can fulfill the entire law of God by loving Him and loving our fellow human beings (Matthew 22:37-40). God is absolutely holy—without any moral or character defect. In fact, the Bible says that God is incapable of doing any evil, despite being all powerful. God is unchangeable. In other words, He does not change any of His attributes or character at any time. Despite humanity's tendency to change its definition of morality, God's moral character does not evolve with the times, but remains constant. (1)
"Who created God? Where did God come from?"
A common argument from atheists and skeptics is that if all things need a cause, then God must also need a cause. The conclusion is that if God needed a cause, then God is not God (and if God is not God, then of course there is no God). This is a slightly more sophisticated form of the basic question “Who made God?” Everyone knows that something does not come from nothing. So, if God is a “something,” then He must have a cause, right?
The question is tricky because it sneaks in the false assumption that God came from somewhere and then asks where that might be. The answer is that the question does not even make sense. It is like asking, “What does blue smell like?” Blue is not in the category of things that have a smell, so the question itself is flawed. In the same way, God is not in the category of things that are created or caused. God is uncaused and uncreated—He simply exists.
How do we know this? We know that from nothing, nothing comes. So, if there were ever a time when there was absolutely nothing in existence, then nothing would have ever come into existence. But things do exist. Therefore, since there could never have been absolutely nothing, something had to have always been in existence. That ever-existing thing is what we call God. God is the uncaused Being that caused everything else to come into existence. God is the uncreated Creator who created the universe and everything in it. (2)
Who is God... He is Forgiving.
We sin. We tend to do things our way instead of God's way. And he sees it and knows it. God does not merely overlook such sin, but is prepared to judge and condemn people for their sin. However, God is forgiving and will forgive us from the moment we begin a relationship with him. Jesus, the Son of God, paid for our sin with his death on a cross. He rose from the dead and offers us this forgiveness.
"We are made right in God's sight when we trust in Jesus Christ to take away our sins. And we all can be saved in this same way, no matter who we are or what we have done... We are made right with God when we believe that Jesus shed his blood, sacrificing his life for us." (Romans 3:22,25)
Who is God... He is Honest.
Just like a person who lets you know their thoughts and feelings, God clearly tells us about himself, the possible difference being, he is always honest. Everything he says about himself, or about us, is reliable information. Truer than our feelings, thoughts, and perception, God is totally accurate and honest in what he says. Every promise he makes to us can be fully counted on, he means it. We can take him at his word.
"The unfolding of your words gives light;
it gives understanding to the simple.
Your word is a lamp to my feet
and a light to my path." (Psalms 119:130,105)
Who is God... He is Capable.
How would you like to be always 100% right, about everything? God is. His wisdom is unlimited. He understands all the elements of a situation, including the history and future events related to it. We do not have to update him, counsel him or persuade him to do the right thing. He will, because he is capable and his motives are pure. If we trust him, he will never make a mistake, never undercut us or deceive us. He can be fully trusted to do what is right, in all circumstances, at all times. (3)
"No one whose hope is in you
will ever be put to shame..." (Psalms 25:3)
