Everything that God has done for us is in preparation for what He has for us. “God himself has prepared us for this, and as a guarantee he has given us his Holy Spirit,” as 2 Corinthians 5:5 says. The Holy Spirit is proof that God works in our lives and is preparing more for us.
The Holy Spirit is our advocate and our intercessor. He is the middle man between us and God. He has made a way for us to communicate with the Father. This is why the Holy Spirit was sent to live in God’s people. Before Jesus went up to heaven to be with the Father in Acts 1, He said that He was sending the Holy Spirit so that we could be His witnesses. The Holy Spirit was our guarantee that we were meant for more than this world has to offer. We know that He is preparing us for the rest of our lives into eternity. When we became saved, He placed His Spirit inside our hearts so that we could be a testimony for Him. We can spend the rest of our lives living here on earth with the Father and telling others about the joy we have. What a great purpose.
We will know how to speak to others about Him because He is preparing our hearts for that. He uses the Holy Spirit to give us the words to say and when we pray for others, He speaks on our behalf.
