In Genesis 12:1 "The LORD had said to Abram, "Go from your country, your people and your father's household to the land I will show you." God's first command was to "Go from your country." Before Abram could ever go anywhere he first had to leave where he was at.
When Jesus called his disciples to come with him, they first had to leave their fishing boats and nets. They had to leave their old lives behind so that they could follow Christ.
God calls us to come and follow Him. He asks us to be willing to leave our old lives and enter into a new life. Just as you can not go into one room without leaving the room you are in, you can not enter into a life with Christ, without leaving your old life behind.
There are many people who long for changes in their lives. They want something better, more satisfying and new. What they don't want is to leave what they have now behind. Few people are willing to leave what they know they have, even if it is not good for them, for something they have not even seen.
When we look upon what we have in our hands now, we are scared to lose what little we have for the promise of something greater that we do no see. We need to look up from our hands and into the face of God. What God promises, God does. When God promises rich robes for rags, He fulfills that promise. God never fails. Trust God. Leave the slavery of your land and go into the promised land of God's riches.
