Jesus said that His disciples would do the same things He did while on the earth and more, because the Holy Spirit would come and live in every Christ follower, not just in Him. The reason for that indwelling was so that we would be able to be instructed by God as far as how to live and spread His gospel. Pastor Mark is teaching about the necessity of having the Spirit being active in us. It’s impossible to live the life God intends us to live without being indwelt by the Holy Spirit. It’s critical that we seek Him out and ask Him to live through us to touch the lives of those around us.
