reflect and refract

Was reading a devotional last night and it talked about being Christ like and reflecting the image of God, etc. Then I remembered in secondary school I used to like these similar sounding words that were found in the same chapter of the science textbook, in this case reflection and refraction. Others include mortality and morbidity, infection and infarction, etc. etc.
And it dawned on me that many people just talk about being a reflection of God. Like a mirror, when light comes at a 20° angle, it reflects of in a 20° angle. The exact same light bouncing off. I felt that was important to God, because I am made wonderfully in his image. And I want to be more and more like Him, as it was said, He must increase and I must decrease. So between me and God, I want to reflect Him.
But I felt I was more important for me to refract towards others. Refraction is when ‘white’ light hits a prism and it comes out the other side in 7 colours like the rainbow. Actually there are more than 7 colours as it is a continuous shade of merging colours, just that people say that to make it easier to define. I feel that everybody is different and have different needs at different times. To reflect means to send back whatever you had with its exact same properties. When you look at the mirror and see your reflection, if your skin is yellow, the mirror shows you yellow, if your shirt is green, the mirror shows you it is green. Pure and truthful.
But 1 size does not fit all. People of all walks of life sometimes need the subtle shades. An old lady may need a helping hand to carry boxloads of stuff, another needs counseling or guidance, your neighbor may be in desperate need of financial assistance to see a doctor.
If I am able to take the light of God that shines on my life and refract that into different people with different needs, then I am fulfilling my life. Can I be that helping hand, that listening ear, that provider? If so, then when I do so to the least of my brothers, then I am conforming to the image of God, for God is Jehovah Rohi, Jehovah Jirah, and Jehovah Rophe.
