How can I know that God exists?
Have you seen my phone? I found it while walking down the street the other day. All the different pieces just came together out of nowhere and formed this phone on the sidewalk at my feet. … I can see that you don’t believe me. Well, if you don’t believe that a phone could come together on its own, how then can you believe that you — something far more beautiful and complex — came into being without a Creator?
How can a man become God?
It would be impossible for a human being to become God. But it would not be impossible for God, who is almighty, to become a human being. The belief that God became a man and died to save us sets Christianity apart from all other religions.
How can there be three persons in one God?
The Holy Trinity is a mystery which we can accept only through faith. … It might be helpful to think of the Trinity in terms of a family. The Smith family, for instance, consists of three persons, yet there is one Smith family.
If God is good, why do innocent people suffer and die; why are there natural disasters?
God did not create us to suffer; He created us to live and be happy with Him forever in heaven. Suffering came into the world when our first parents, Adam and Eve, disobeyed Him. Because God is good by nature He could never be the cause of evil. He does permit evil to occur, but always in order to bring about a greater good.
The Bible says we will become gods; we will "come to share in the divine nature" (2 Pet. 1:4).
— Common to Mormons and New Agers —
We have to be careful in interpreting Scripture from a translation that is removed from the original culture and language. Also, when interpreting Scripture, we need to be careful not to interpret one verse out of context of the whole. The rest of Scripture tells us there is one true God, not many. Isaiah 44:6, for instance, says, "I am the first and I am the last; beside me there is no god." So while it's true the saints in heaven will share in God's divine nature, becoming like Him in a limited sense, their essence will not be changed. They will have a glorified human nature, not a divine nature. He will remain God and they will remain His creatures.

John 1:1 says, "In the beginning was the Word, and the Word was with God, and the word was a god.”
— Common to Jehovah's Witnesses, based on their New World Translation of the Bible (selectively edited) —
You have translated that verse incorrectly. It should say "and the word was God," not a god. The proof of this is John 20:28 in which Thomas calls Jesus "My Lord and my God!"
- Thomas was just expressing surprise at seeing Jesus.
If that’s the case then Jesus would have rebuked him for taking the Lord’s name in vain.
Why do Catholics have crucifixes when Jesus rose from the dead?
Because Jesus is risen is it wrong for us to remember that He died for our sins? Paul said in First Corinthians 1:23, "we proclaim Christ crucified." Why do you condemn us for this?
Why are Christians against the Theory of Evolution?
There are some parts to the Theory of Evolution which the Church can accept, such as the idea that life develops from simple into complex forms. But we see this as God’s chosen mode of creation, not as proof of His nonexistence. The fundamental flaw with the Theory of Evolution is that it can only hope to explain how life developed after it arrived, but is powerless to explain how it got here in the first place.
The Trinity is a three-headed monster created by medieval Catholicism.
— Common to Jehovah's Witnesses and Mormons —
Isaiah 44:6 proves there is one God, not many: "I am the first and I am the last; beside me there is no god." Yet in Genesis 1:26, God speaks in the first person plural, saying, "Let us make man in our image, after our likeness," suggesting He consists of more than one person.
