Check out the following Bible verses:
Hebrews 11: 6 – But without faith it is impossible to please God, for he who comes to God must believe that He is and that He is a rewarder of those who diligently seek Him.
Romans 5: 1 – Therefore being justified by faith we have peace with God through our Lord Jesus Christ
2 Corinthians 5: 7 – For we walk by faith, not by sight
Ephesians 6: 16 – Above all, taking the shield of faith with which you will be able to quench the fiery darts of the wicked one. (shield of faith is part of the armour of God – Ephesians 6: 10 -17)
These are just some of the many ways faith plays a role in your life.
