The late G.K. Chesterton answered the question quite simply, Christians. When we act contrary to the Gospel of Jesus Christ, we give a verification to those who are not a Christian. They think of all Christians as hypocrites. At times, this can be a stumbling block that prevents them from salvation. Shame on us!
At the same time, though, saints are the ones that make the largest case for Christianity. They are not hypocritical. No, their actions and words are the same. Their lives lead many to salvation.
Now, what stands in our way of us becoming saints? Ok, that may sound like a large task. However, we must realize that we are either going to be saints or going to Hell. Everyone in Heaven is a saint. Are they all canonized like the saints we have come to know? No. God provides the miracles for those saints to be canonized, to be a great symbol for us, an example.
We can be great examples for those around us. Sometimes that means admitting to our faults. If we admit our failures to those most influenced by them, we become good examples again. They see hypocritical action or words, but they also now know we are aware of them too and working to correct them. We are sinners in need of a Savior, and we were provided the best and unimaginable Savior!
Thank you Jesus! Jesus, help those who have witnessed my hypocritical actions or words. Do not let me be a stumbling block for others' salvation.
