Sorry all, for being side tracked a little.
I already knew explaining and debating wouldn't work here, because
THAT IS MY POINT in the first place.
But every time someone asks me questions about the bible, I make a same mistake and try to debate and come up with excuses for my God. my mistake.

Let's get back to OP.
Just in case you are wondering why people believe in God.
If you are not interested, please do not start reading, you are wasting your time.
So, in order to believe in God.
Like I said earlier, God chooses us, not we do.
"
You did not choose me, but I chose you and appointed you to go and bear fruit" (John 15:16)
You probably know how Saul was converted and became apostle Paul (Acts 9), basically Christ showed himself to Paul, on his way to capture and murder Christians.
You probably know what Jesus said to peter and his brother, all he said was "Come, follow" then they dropped what they were doing and followed him.
You probably know what Jesus told us(Christians), "
Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.” (Matthew 28:19-20)
It surely doesn't sound like "Go, make excuses for me, explain them, debate with them, use all your logics to make them believe........"
NO NO NO that is not our job.
I already told you how I became a Christian, I listened and I believed, that is all.
Ask any Christians you know how they became believers, I guarantee you, no Christian will say "I believe in God, because whole bible makes sense, virgin Mary, taliking snake and all.",
Indoctrinated? no, how are you going to explain some pastor's kids that are atheists?
Illogical? no, how are you going to explain professors in logistics that are believers?
moral? no, how are you going to explain two robbers were crucified with Jesus, and only one of two believed?
Free will? maybe, but how are going to explain apostle Paul's case? did paul want to believe in Christ?
"
Does not the potter have the right to make out of the same lump of clay some pottery for noble purposes and some for common use?"(Romans 9:21)
So if you are asking Christians "why won't god heal amputees?", you are asking the wrong crowd, because we don't know.
Who told you we,(Christians) are God's advocates? We are his followers.
You are asking sheep, you have to ask the shephard (if he listens to you)
So next time you have a chance to talk to a Christian, ask him/her "how did you start believing?" or "why do you believe?"
Let me say this again, Jesus said "
My sheep listen to my voice, I know them, and they follow me"(John 10:27)
