I like the saying – “If you can explain God, He wouldn’t be God.”  People try to explain the Holy Spirit and His work. Believers in Christ Jesus are given the gift of the Holy Spirit in their lives to help them in their growing relationship with God so they may encourage others in their walk with God.  The Bible tells us in 1 Corinthians 12-14, that the Holy Spirit gives believers spiritual gifts of encouragement, hospitality, faith, healing, and many more gifts.  And in Galatians 5:22-23,

 “… the Holy Spirit produces this kind of fruit in our lives: love, joy, peace, patience, kindness, goodness, faithfulness,  gentleness, and self-control. 

In John 3, Jesus is talking to Nicodemus, a Jewish Religious Leader.  Jesus explained to Nicodemus how a person can enter the Kingdom of God. He said, . . .

“without being born of water and the Spirit.  Humans can reproduce only human life, but the Holy Spirit gives birth to spiritual life.   So don’t be surprised when I say, ‘You must be born again.’  The wind blows wherever it wants. Just as you can hear the wind but can’t tell where it comes from or where it is going, so you can’t explain how people are born of the Spirit.”  John 3:5b-8 [New Living Translation]

The Holy Spirit isn’t easy to explain, and neither is how He works to change people’s hearts to believe.  That’s where FAITH comes in. We need to surrender our hearts and believe that Jesus Christ is the one and only Son of God. He died to forgive us of ALL of our sins. All we need to do is BELIEVE. When we do that the Holy Spirit lives in us and begins to change us to be more and more like Jesus every day.
