If your life was $1000 bill and you gave it to God, what if He multiplied it and gave it back to you as several thousand $1 bills? Each day you would be asked to give Him $1 to represent your daily commitment to Him. The giving of the $1000 would represent you giving your life to Him for His gift of salvation. In no way does this imply that salvation can be bought with money because it cannot be purchased or earned. God giving you several thousand $1 bills in return represents how much more you will have when you give your life to him and the free will that He gives you to choose everyday whether you want to live that day for Him or not. Each $1 will represent a day of your life. We only have so many. We will have the choice to give it to him to multiply it and use it or to keep it and waste it. How many days have you already wasted? Do you wake each morning and take up your cross to follow Jesus? How will you spend your remaining days/dollars?
If you have a $20 bill to represent your day, $1 for each hour, how much of it will be given to Jesus? How well are you spending your time?
