How do we know the doctrine of bearing one's cross is true?

Jesus's statement in Luke 14:27, "And whosoever doth not bear his cross, and come after me, cannot be my disciple," illustrates the transformative nature of following Him. The cross symbolizes death to self and the renunciation of worldly attachments. Just as crucifixion was a public declaration of one’s impending death, so too is taking up our cross a public commitment to die to our former way of life. This doctrine is affirmed throughout the New Testament, particularly in Romans 6, where Paul writes about being baptized into Christ's death, emphasizing our spiritual union with Him in death and resurrection. Embracing this teaching reveals the serious nature of discipleship, as it requires a willingness to endure trials for the sake of Christ.
