"When He had called the people to Himself, with His disciples also, He said to them, 'Whoever desires to come after Me, let him deny himself, and take up his cross, and follow Me. . .' " (Mark 8:34, NKJV)
"And he who does not take his cross and follow after Me is not worthy of Me." (Matthew 10:38, NKJV)
"Then He said to them all, 'If anyone desires to come after Me, let him deny himself, and take up his cross daily, and follow Me. . . ' " (Luke 9:23, NKJV)
"And whoever does not bear his cross and come after Me cannot be My disciple." (Luke 14:27, NKJV)
It is indeed remarkable that Jesus made this declaration to His disciples two years before He was crucified.
