Luke 16:10-11

He who is faithful in what is least is faithful also in much; and he who is unjust in what is least is unjust also in much.  Therefore, if you have not been faithful in the unrighteous mammon, who will commit to your trust the true riches.  

Our integrity before God is essential to measure our growth as Christians.  We cannot advance if we can’t be trusted with the new responsibilities, and the little things do matter with God.  Even the simple things matter to God because the little things add up.  When we are faithful and trustworthy, we will gain in every area of our lives.
