Our reason for being is to do things that are honoring to God, our Creator. Our purpose is to bring peace, share love, kindness, gentleness, and goodness to others. To spread His words to everyone we come accross with.
To uplift others and help those in need. To be an encouragement to those who feel discouraged. To serve and please our Father in Heaven in everything that we do. So, don't ever think that you are of no value.
