This book is about the invisible hand of God at work. But if “no one has ever seen God” (John 1:18), and God is a “Spirit” (John 4:24), then how can anyone know anything about the invisible hand of God at work? Although God’s hand is unseen, it accomplishes great and mighty things as recorded in the Bible.When God’s people, the Israelites, crossed the Red Sea and the Jordan River on dry ground, it was because the invisible hand of God was at work performing miracles for His people. Joshua told the Israelites why God did these amazing miracles: “He did this so that all the peoples of the earth might know that the hand of the Lord is powerful and so that you might always fear the Lord your God” (Joshua 4:24).When scores of people turned to the Lord in the book of Acts, it was because the invisible hand of God was at work. “The Lord’s hand was with them, and a great number of people believed and turned to the Lord” (Acts 11:21).Many of God’s servants wrote about God’s hand being upon them. David declared, “For day and night Your hand was heavy upon me” (Psalm 32:4). He also wrote about God’s hand of guidance in his life. “If I rise on the wings of the dawn, if I settle on the far side of the sea, even there Your hand will guide me, Your right hand will hold me fast” (Psalm 139:9-10).Ezekiel, the prophet, also wrote of the strong hand of the Lord being on him (Ezekiel 3:14,22).Although the biblical references to “the hand of God” or “the hand of the Lord” were metaphorical, those who wrote about the invisible hand of God experienced His hand working amazing effects in their lives. And just as we cannot see the wind, but we can experience its effects, even so we cannot see God’s hand at work, but we can experience the effects of God’s hand upon our lives as His children.I felt compelled to write this book. Psalm 145:4 declares, “One generation will commend Your works to another; they will tell of Your mighty acts.” As Christians, we are to pass on to the next generation what we have experienced of the invisible hand of God at work in our lives. We are to declare His mighty acts to the next generation.Do you desire to experience more of the invisible hand of God at work in your life? As you seek to know, love and obey Him, be prepared. His hand will work in unexplainable ways and you will conclude that only God could have done these things and you will want to share with others what He did in your life.It is my prayer that the next generation will experience the invisible hand of God at work in their lives as I have experienced His hand at work in my life. If that prayer is answered, then I will praise Him for His “mighty acts” which He has done not only in my life, but in the lives of countless multitudes throughout the ages. To God be the glory.
