Why is believing in Jesus essential to understanding God's will?

The belief in Jesus Christ is not only foundational for salvation but also essential for grasping the comprehensive nature of God's will. In John 6:40, Jesus articulates that the Father's will is for those who see the Son and believe in Him to have eternal life. This belief is an act of faith in understanding God's sovereignty and His redemptive plan. Christianity teaches that it is not through human effort or merit that one approaches God, but through faith in Christ, who fully accomplished the work needed for salvation. Therefore, when believers see Jesus for who He truly is—in His glory, power, and sacrificial love—they are living demonstrations of understanding and participating in God's will.
