If you are confused about the trinity, think of it this way.  You believe in an afterlife, right?  Where is your spirit that I can touch that will go to heaven or hell? I can’t.  Also, where are your thoughts and imaginations?  I can’t touch them.

As humans we are body, soul and spirit.  We, like God, are three in one.  These are three distinct parts of our existence and yet explicably entertwined.  Just like God.

The God of the Bible is triune in nature.  He is Father, Son and Holy Spirit.  But some ask, where in the Bible does it say that the Holy Spirit is part of God’s triune nature? Acts 5 is one of those places.

As we saw earlier, Ananias and Sapphira were lying before God and the apostles.  Look what the text says (Acts 5:3-4).

Then Peter said, “Ananias, how is it that Satan has so filled your heart that you have lied to the Holy Spirit and have kept for yourself some of the money you received for the land?  …  You have not lied just to human beings but to God.”

Lying to the Holy Spirit was the equivalent of lying to God.

But is this the only place?  Where we see the Holy Spirit as being equal to God?  Let’s look at Matthew 28:19.

Did you notice something?  It doesn’t say “names” but in the “name” of the Father, Son and Holy Spirit.  This is three in one.  Again.
