Teshuvah

King David prays to God asking God to not remember the sins of his youth. How many of us do stupid things when we are young? The young think they are invincible, their energy is incredible but they lack knowledge and wisdom unless they come from a family that gives good instruction. Who doesn't worry about their kids once they go away to college. We've heard about the stories. Teens gone wild. Drinking and sex is their past time.
It's very concerning given that some of these teens destroy their futures.  I have told my kids that what ever decisions you make can determine the rest of your life!
Yet, who has not been a sinner? We all fall short of the mark. Whether it be how we act towards others in what we say or do or whatever mitzvah (mitzvot; plural) we ignore.
There comes a time when a lot of people recognize there needs to be change within themselves. If they have a love for God, they desire to change not only for God but for themselves. Some take longer than others in this process of change. However long it might take, being persistent is rewarding. People can and do change, it's called growth. God tells us (through His Word) that if we call upon Him and repent with a sincere heart, He hears us and he forgives us.
Being young isn't easy, but being young with a guilty heart is a good sign that teshuvah will take place with success. Guilt brings repentance and repentance turns us around to obedience to God. What a refreshing and beautiful thing repentance is and brings us closer to our Creator.
