You can explain the concept of the Holy Spirit-filled life using this simple recipe for chocolate milk.
Step One: Add chocolate syrup to a glass of milk.
Step Two: Stir.
In the Christian life, the "chocolate" of the Holy Spirit is added at the moment of salvation. Ephesians 1:13 explains that we receive the Spirit when we trust in Jesus as our Savior. The Spirit never needs to be added again.
However, in milk the chocolate syrup settles on the bottom of the glass until the milk is stirred up. Then the appearance and taste change completely.
Similarly, a Christian cannot experience the sweetness of spiritual change and growth until he or she asks the Holy Spirit to be in control. Then the Spirit produces godliness in a Christian's life, as promised in Galatians 5:22,23.
God adds the Spirit when we become Christians, but we must "stir" Him up in our lives daily.
Challenge a Christian by asking, "Are you settled or sweet?"
How can you stir up the Holy Spirit in your life?
When you receive Christ as your Savior and Lord, God gave you an amazing gift -- His very life, breath and power lives in You in the person of the Holy Spirit.
We experience the Holy Spirit's constant help, guidance, comfort as we ask Him and we trust Him to keep on filling us. When we do, we overflow: "May the God of hope fill you with all joy and peace as you trust in him, so that you may overflow with hope by the power of the Holy Spirit" (Romans 15:13).
