This is the chapter pala where Jesus describes the Holy Trinity. I never really fully understood it -- how three personas are one. Here is what Jesus said:
• 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.
• The Companion, the Holy Spirit, whom the Father will send in my name, will teach you everything and will remind you of everything I told you.
Okay, I still don't fully understand it. But it is comforting to hear Jesus talk about it. A priest once said that humans are not capable of understanding the complexity of God's works. Kaya nga hindi tayo god diba? The trinity remains once of those mysteries that as Catholics, we continue to have faith in even when we don't fully understand.
One more thing I like about this chapter are the promises that Jesus said:
• My Father’s house has room to spare. If that weren’t the case, would I have told you that I’m going to prepare a place for you? O diba, wala kang atras, Jesus really wants to be with you in heaven.
• I will do whatever you ask for in my name, so that the Father can be glorified in the Son. When you ask me for anything in my name, I will do it. Kaya pala we say "In Jesus' name" when we pray
• I won’t leave you as orphans. I will come to you. Soon the world will no longer see me, but you will see me. Wait, this comes with a bilin -- and I find it true for me, too, for when I'm gone. Jesus (or me) remains in you because... Whoever loves me will keep my word. That means, you should remain obedient to what the Lord (or I) taught you. Only then can you say that I remain in you.
• and finally.... You have heard me tell you, ‘I’m going away and returning to you.’ If you loved me, you would be happy that I am going to the Father, because the Father is greater than me.
I do hope you read this chapter for yourself. Let me know what key learnings you got from it.
