One of the hardest ideas to understand in Christianity is the Trinity, the idea that there really is only one God, but in three distinct persons. It is a topic we may never fully understand, but it is one that makes the best sense of what we see in the Bible. Look, for example, at this passage in John
Jesus replied, “Don’t you know me, Philip, even after I have been with you all this time? Whoever has seen me has seen the Father. How can you say, ‘Show us the Father’? Don’t you believe that I am in the Father and the Father is in me? The words I have spoken to you I don’t speak on my own. The Father who dwells in me does his works.”
In this passage Jesus lets us know that through him the Father is made known. What Jesus did and said while he was on earth was exactly what the Father wanted him to do and say because it was actually the Father who was speaking and working in the Son.
This is confusing, but comforting. Especially when we look at what Jesus says a few verses later. As he is talking about the Holy Spirit coming to his followers, he says
Jesus answered, “Whoever loves me will keep my word. My Father will love them, and we will come to them and make our home with them” (14:23).
Now this idea is expanded to the Holy Spirit as well. When we receive the Holy Spirit in our lives as we become believers and followers of Jesus Christ, we have God the Father, Son, and Holy Spirit dwelling in us, making their home with us.
Certain traditions within the history of the Church have said we should have “Jesus in our hearts” or the “indwelling of the Spirit.” What Jesus says here is beyond all of that. Jesus says that when we become Christians, the entire Trinity dwells in us. The Father, Son, and Holy Spirit reside with us and have fellowship with us.
I find this very comforting because I know there are times when it seems like God is remote and distant, like God does not know or understand what is happening in life. With this statement, Jesus reminds us that no matter what we go through in life (and since this was right before he was arrested, he was preparing his apostles for some very difficult times and persecutions) Father, Son, and Holy Spirit will be with us.
Thanks be to God!
