Jesus compared the Holy Spirit to the wind (John 3:8). Like the wind, the Holy Spirit is always flowing. To be filled with the Holy Spirit simply means that we live our lives like a ship with a sail. When our sail is up, we allow the Holy Spirit to fill us, direct our life, and lead us where he wants us to go, to become who he wants us to be, and to do what he wants us to do. Our sail comes down through unrepentant sin, unbelief, clinging to lies rather than truth, foolish doctrine, and bad life decisions, all of which “quench the Spirit” (1 Thessalonians 5:19). Be filled with the Holy Spirit. Put your sail up. Repent, believe, read your Bible, pray, submit, and be in community with God’s people. In this way, God will fill you, lead you, guide you, and empower you… Without the Holy Spirit, Christianity becomes nothing but a list of dos and don’ts. You either live a decent life and become proud as a result, or you fail to measure up and fall into despair. Neither result leads to the kind of humble joy that comes from the Holy Spirit.
