And the believers were filled with joy and with the Holy Spirit. [Acts 13:52 (NLT)]

Zebra Longwing butterflies (Heliconius charithonia) live in hammocks and damp forests. Unless they are resting on a plant, however, they are often difficult to spot. Unlike most butterflies, they don’t stay in the sunlight for long. I may see their shadows on the boardwalk but, when I look up, they quickly vanish into the shade they prefer. With their yellow and black colors, shallow wingbeats and languid flight, they float through the woods and often seem to be little more than flickering sunlight glimmering through the trees.
Oddly, I think of the Holy Spirit whenever I get a glimpse of these beautiful creatures. Just as I’ll probably never hold one in my hand, I have difficulty grasping the concept of the Holy Spirit. Nevertheless, I know they both exist and bring me joy. There are times it’s difficult to catch sight of the winged zebras and, unfortunately, there are times I have difficulty detecting the Spirit. Nevertheless, just as I know the butterflies are in the woods, I know that He is present. Some days are better than others when it comes to spotting the Longwings and some days are better than others when it comes to sensing the Holy Spirit’s presence. If I’m jogging down a trail, I’ll never spot the butterflies and, if I’m rushing through life, it’s just as easy to overlook the Holy Spirit.
While I can blame the season, weather, light, or location for not seeing a butterfly, I have only myself to blame when I fail to perceive the Spirit. The times I feel devoid of His presence are when I neglect Scripture and prayer—the times I become so busy with the “me” and “my” of life that I don’t leave room for Him. They are the times I refuse to accept God’s control of my circumstances, ignore His direction, or don’t want to hear His conviction of my unacceptable behavior. Most often, however, I can’t feel the Holy Spirit because I’ve done something that grieves Him. Things like anger, resentment, jealousy, guilt and pride serve as barriers to feeling His presence. Fortunately, unlike the butterflies that disappear as they float through the woods, the Spirit will never leave me, even when I’ve disappointed Him.
In perfect unity with God the Father and God the Son, the Holy Spirit is the power of God that dwells within every believer in Jesus Christ. Just as it’s likely that I’ll catch a glimpse of Zebra Longwings on a certain boardwalk through the mangroves, I’m sure to feel the Spirit’s presence when I walk in His ways throughout the day.
You might as well try to see without eyes, hear without ears, or breathe without lungs, as to try to live the Christian life without the Holy Spirit. [D.L. Moody]

The culture of the 1st century was agrarian in nature so the analogies used by Jesus and the evangelists often were those of agriculture – seeds, soil, fruit, and vines. For example, when writing about the characteristics in the lives of those who follow Jesus, Paul spoke of the fruit of the Spirit. But, if Paul were writing to modern industrial society, he might have used a different metaphor. Instead of the fruit of the Holy Spirit, we might have the Spirit’s toolbox. Rather than fruit, we’d have God’s tools to help us to build His Kingdom. The saw in the box would be God’s peace that cuts worry and fear out of our lives. The sandpaper would be kindness as it smooths out life’s rough edges. Protective gear like safety goggles and steel-toed shoes would be the self-discipline that protects us from sin. Duct tape and WD-40 would be as essential as love, a flashlight would shine our joy, and we’d have clamps to hold us tight to the faith. God’s word would be our blueprint and, instead of being connected to a vine, the power tools would be plugged into the Holy Spirit’s power. Regardless of the metaphor, the Holy Spirit provides us with what we need to be more like Christ.
And I will give you a new heart, and I will put a new spirit in you. I will take out your stony, stubborn heart and give you a tender, responsive heart. And I will put my Spirit in you so that you will follow my decrees and be careful to obey my regulations. [Ezekiel 36:26-27 (NLT)]
Jesus said to him, “For sure, I tell you, unless a man is born again, he cannot see the holy nation of God.” Nicodemus said to Him, “How can a man be born when he is old? How can he get into his mother’s body and be born the second time?” [John 3:3-4 (NLV)]
