Why is having faith in Christ important for Christians?

Faith in Christ is paramount for Christians because it facilitates a spiritual connection to Him, enabling believers to receive the salvation that He accomplished through His righteousness and sacrifice. Philippians 3:9 emphasizes that believers are found in Christ, not having their own righteousness, but that which comes through faith in Him. This faith allows Christians to rest in the assurance that their sins are washed away by Christ's blood, as stated in Hebrews 9:22. It is through faith that we are justified, not by our works, but by the grace of God that draws us to trust in the finished work of Christ on our behalf.
