It is so important for us to testify while we are having a normal conversation with people. Most people don't want to "sit down and listen to a message" But as we have a conversation with them we are able to share with them how they are loved by a Heavenly Father. We try to come up with short truths we can share with other people while we're contacting that day and we call them DC Dimes.
God has control of so many things: the stars, the weather, the birds and bees, etc. One thing he doesn't have control of is our agency. He wants to help us change but he can't until we hand our full heart and mind to Him and say, like our Savior, "Not my will, but thine be done." Only then can He help you change into the person you want to be.
