"I pray that God, who gives hope, will bless you with complete happiness and peace because of your faith. And may the power of the Holy Spirit fill you with hope." Romans 15:13 CEV
Do you understand where hope comes from? Do you think its something that you can just make up on your own? Hope, true hope, cannot be conjured up by man's effort. No. It is God's gift to us by His Spirit.
And while we need hope, we are not saved by hope. We are saved by faith. But with salvation comes hope.
The cool thing about the trinity is this--that even though there are three distinct individuals, each with their own strengths and roles--they can also be squished into one--one AWESOME, complete God.
As hope sustains us in trials and tribulations, the Holy Spirit helps us when we pray. Have you ever have a relationship with someone that was so close that there was times that you didn't even need to actually speak words, yet you knew what the other was thinking? Well, that's how the relationship between the Holy Spirit and God our Father and Jesus the Son is. Their relationship is so close that their prayers to each other need not even to be spoken out loud. They just know.
Does the thought of the Holy Spirit scare you? It used to me. But now, I am slowly developing a whole new sense and appreciation of it. You see, The Holy Spirit is a part of God. It is one of the bridges between Him and us. Jesus was the other. And Jesus isn't scary so why should the Holy Spirit be?
