How can someone be close to Christ yet still be lost?

The story of the two thieves crucified alongside Jesus serves as a profound warning about proximity to Christ without true faith. One thief rejected Jesus while the other turned to Him in faith, showing that mere nearness does not equate to salvation. In Luke 23:39-43, we observe that despite being physically adjacent to the Savior, the lost thief ultimately perished because of his unbelief. Hebrews 3:15 warns us not to harden our hearts but to respond to Christ. This underscores the importance of personal faith and repentance; it is not enough to be familiar with Jesus or His teachings. What matters is a heart turned towards Him, recognizing Him as Lord and Savior.
