A quite insignificant way to increase in what you have is to effectively manage the seemingly little put in your care, take note that manage here doesn’t mean to hold on to what you have without giving.
Now see from scriptures Luke 16:10 He that is faithful in that which is least is faithful also in much: and he that is unjust in the least is unjust also in much.
This is to say that the way you handle resources now is a reflection of how you would later on when you have a lot more at your disposal. Don’t be like they that say when I have more, I will handle better. No! The true test of your effectiveness at managing the resources you haven’t seen yet is in the way you handle that which you have within your reach now.
