Bible study

I have been looking up scripture dealing with lying and telling the truth. I haven't even read through most of them and i am quickly seeing Why it is one of the ten commandments. When we lie to people we think that it won't hurt anyone. that it just a simple little lie just so we can save ourself. (With me it was because i was scared that my friend would get mad at me and not want to be my friend anymore. ) Ever since i confessed to my friend what i had done i have been thinking about all the little simple lies that i said to protect myself. I can see how each one slowly has been burning away are friendship. To us in the moment they seem like something that isn't going to harm anything until the truth comes out and then those little sparks of lies turn into one big giant fire that only God will be able to put out. Its all i have been thinking about.
You can lose alot of things and be ok but once you lose trust it is almost impossible to gain it back. I have thought over and over how can i prove that i can be trustworthy again. How can i show people that i care about that i am an honest person and that i am done lying. How can someone gain trust once they lost it. So far all i can find is to keep praying, stay trustworthy, and be patient. It isn't going to happen over night but if God wants it to be then it will be. I keep thinking about how me lying has caught me to hurt and i am sure the person that gets lied to hurts so much more . Well i am going to continue on to doing this study maybe i will learn so much more then i already have
