1) We were created by God to worship Him through belief and practice, which involves gaining knowledge of God by reflecting on His names and following His guidance.
2) Our responsibilities include fulfilling the purpose of our existence by worshipping God, fulfilling our trust in Him, establishing justice, and serving others.
3) The goal of life is to please God by increasing our faith and practice until our eventual death and return to Him in the hereafter, where we will face eternal rewards in paradise or punishment in hell based on how we lived our lives.
