The lamp of the body is the eye. If therefore your eye is good, your whole body will be full of light. But if your eye is bad, your whole body will be full of darkness. If therefore the light that is in you is darkness, how great is that darkness! (Matt 6:22-23)
Within this portion Jesus teaches us the importance to look at things in the right manner. Sin casts a shadow in one’s heart, so much so that one cannot discern correctly. In such a case even the good that others try to do will be counted as an offence. If you find yourself in such situation, there is hope. Look to Christ, the Light of the World. He is full of truth and full of grace. It is at the cross that we find healing.
