Another Prayer Answered

So I worked this week on Tuesday and Friday. What a surprise when I arrived Tuesday and he had already filled my position. She appears to be a very nice lady and works two other jobs as well. She also has two almost grown children. She worked with me both days and I can leave with peace now. I am definitely leaving him in a better position than when I arrived. I can't say I have not made any mistakes because I know that I am not perfect but I have done my best. And hopefully I have made a positive impact. Thanks for praying....God always hears and answers...
So now it is on with life and the next adventure. Not sure what lies ahead but I know that God will guide and direct my path. Have you ever experienced that question in your heart, am I doing all that I am suppose to do? I understand that God leads and guides. Some times I just question my ability to hear what He is saying. When I look back at some of the decisions I have made, I know that I prayed and sincerely sought His will and way, so how did I go so wrong? Would love to hear your thoughts!
