Why is looking unto Jesus crucial for Christians?

In Hebrews 12:2, Christians are instructed to look unto Jesus, the author and finisher of our faith. This act of focusing on Christ is imperative because He alone is the source of our spiritual vitality. By keeping our eyes fixed on Jesus, we are reminded of His completed work on the cross, which assures us of our salvation. He endured great suffering for our benefit, despising the shame, and now sits at the right hand of God, interceding for us. This understanding fosters a deeper reliance on Him through prayer and trust, allowing us to endure trials and remain steadfast in our walk.
