 What exactly is the purpose of the Holy Spirit and what does it do in our lives as Christians? Well Paul says it is God who established us in Christ and has anointed us and put his seal and given us the Spirit in our hearts as a guarantee. Some will say as even a down payment. The King James uses the term earnest. What does that remind you of? Well that's like a down payment that you put and the purpose of a down payment is not to forfeit it or even have the possibility of it being forfeited. It is to make sure that you get what has been purchased. You put down payments and deposits on cars, houses, hotels, things like that. Well God does the same thing with the Holy Spirit and he keeps us. He's a seal and he brings us through. That's why the Bible says that he who began a good work in us is faithful to bring us through. And how does he do so? Through the Holy Spirit. Amen.
