There are too many unhappy born-again, Spirit-filled believers who don't know what it's like to remain full of the Spirit of God by acknowledging Him and pursuing His ways daily. The Holy Spirit is in them, but they don't let the evidence of it show up in their normal, day-to-day life.
It is possible to fill a glass with water without filling it to full capacity. Likewise, when we are born-again, we have the Holy Spirit in us, but we may not yet be totally filled and have the evidence of His power in our lives.
Acts 4:31 reports that when people were filled with the Holy Spirit, they spoke the Word of God with freedom and boldness and courage.
It does not please God when people leave Him out of their daily lives and then follow religious formulas to try to appease Him. Instead, He wants us to live the Spirit-filled life of freedom, boldness and courage.
I urge you to let God work freely in every area of your life through the power of the Holy Spirit.
