Why is it important for Christians to have a single eye focused on Christ?

In Luke 11:34-36, Jesus teaches that the eye is the lamp of the body, meaning what we focus on directs our lives. A single eye, or a heart solely set on Christ, fills our being with light, allowing us to recognize and navigate obstacles in our spiritual journey. When distractions or sin cloud our vision, we may stray from the truth and face spiritual danger. Thus, maintaining a singular focus on Christ, who is the source of all wisdom and guidance, is crucial for believers to grow in faith and bear fruit for His glory.
