Trinity: If Jesus is God, then who did he pray to? Did Jesus pray to himself? -

One Muslim polemic goes like this.
If a Muslim asks: "Is Jesus God?".
 Don't go for the trap of simply saying "yes.", because then you will open the door to a series of unproductive questions like: "Does God pray to himself"?
The Greek language was powerful enough to express "Jesus is God", but it does not say that.  You only find more nuanced statements such as this one:

For in him dwelleth all the fulness of the Godhead bodily.
--Colossians 2:9 (KJV)

There is a fundamental difference in terminology:  When Muslims say God they mean their one god, or, like God The Father.
When we say God we refer to the being who is manifested in three persons.
The confusion is that we also say "God", meaning God the Father.  Actually all three are equally God.

Jesus brings a Sword, not Peace! +

The Muslim mindset is always trying to find ways to deflect blame from the violence that always seems to follow it.  One way they do this is by quoting the verse highlighted below:

34 "Don't think that I came to send peace on the earth. 
I didn't come to send peace, but a sword. 

35 For I came to set a man at odds against his father, 
and a daughter against her mother, 
and a daughter-in-law against her mother-in-law. 

36 A man's foes will be those of his own household.
--Matt 10:34-36

The Muslim will certainly not quote this verse in context (with vv.35-36) , nor will he point out that the entire chapter 10 of Matthew deals with the persecution that his disciples would suffer.
The best response to a sincere Muslim seeker is just to read all of Matthew 10 together.

The point is that in Matthew 10, the sword represents division, conflict, and persecution that is directed at the disciples of Jesus.

Muslims may been told about this verse:

 Then he said to them, “But now, whoever has a purse, let him take it, and likewise a wallet. Whoever has none, let him sell his cloak, and buy a sword.”
--Luke 22:36

But here is the context, which Muslims have not heard about:

 “For I tell you that this which is written must still be fulfilled in me: 
‘He was counted with transgressors.’
For that which concerns me has an end.”
--Luke 22:37

Jesus also said:

 “Put your sword back into its place, for all those who take the sword will die by the sword. Or do you think that I couldn't ask my Father, and he would even now send me more than twelve legions of angels?  How then would the Scriptures be fulfilled that it must be so?”
--Matthew 26:52-54

Question for Muslims: what verse gives justification for Christians to take up a (physical) sword?
