You may think you're not ready to make a difference in God's Kingdom or that you're too young for others to take seriously. But that's not what God thinks.
At some point, you have to understand your own purpose and significance in the kingdom of God. How does God want to use you? This book uses the Old Testament leader Joshua as a model for stepping up to God's big calling. Before Joshua, Moses was the one who had spoken to God, performed miracles, and challenged Pharaoh. But at some point, Joshua had to come out to the front. So what did he do? How did he step up? And what steps can you take to seize "now" for yourself?
Now is your time. If you will be steadfast and unmovable, and always abound in what God is calling you to do, you'll see that it will not be in vain. He has a plan, a destiny for your life. Now means "not later." Now means "don't wait." God wants to do great things.
