God purpose for our lives is to continue to praise Him with our whole lives. To bring to the world the light which is Christ Jesus. In order to fulfill this purpose, we have to accept our inheritance, which was predestined before time, and allow the Holy Spirit to fill the voids within us. Mathew 5: 13-16 goes on to expand our purpose here on earth by referring to us as the salt (or seasoning) for our fellow people. By living according to God's will in us (to praise Him and tell about His good news), we become like lights in a lighthouse, a beacon of hope for the weary. When people see that you are good and that you have their interest at the heart of your actions (good works), then you give praise and glory to the father, which is our intended purpose on this earth. It makes a continuous circle of praise, glory, praise, glory. Cool!
