第一次戴上我的新眼鏡時，我興奮極了，但在短短幾個鐘頭之後，我就很想丟掉這副新眼鏡。為了適應新的度數，不單是眼睛痠，頭也抽痛，新的鏡架還把耳朵磨疼了。第二天，想到還得戴上新眼鏡，我不禁叫苦連天。為了讓身體能夠適應新眼鏡，我不得不強迫自己，天天戴上它。我花了好幾個星期的時間適應，但在那之後，我幾乎沒有感覺自己是戴著新眼鏡了。

穿戴新的事物是需要花時間調適的，但隨著時間的推移，我們會漸漸地適應，也會覺得它更適合我們，甚至使我們可以看見以前沒看到的事物。在羅馬書13章，使徒保羅教導眾信徒要「帶上光明的兵器」（12節），並操練正確的生活方式。因為這些人雖早已信了耶穌，但似乎陷入了「沉睡」，而且越來越自滿。他們需要從睡夢中醒來，並且付諸行動，行事為人光明磊落，除去一切的惡行（11-13節）。保羅勉勵他們，要披戴主耶穌，在思想及行為上都要變得更像祂（14節）。

我們並不是在一夜之間就能反映出耶穌的慈愛、溫和、仁慈，以及滿有恩典和信實的樣式。這是一個漫長的過程，每一天都選擇「帶上光明的兵器」，甚至覺得不舒服也依然帶上。久而久之，祂會使我們變得更好。

I was so excited to put on my new glasses for the first time, but after just a few hours I wanted to throw them away. My eyes ached and head throbbed from adjusting to the new prescription. My ears were sore from the unfamiliar frames. The next day I groaned when I remembered I had to wear them. I had to repeatedly choose to use my glasses each day in order for my body to adjust. It took several weeks, but after that, I hardly noticed I was wearing them.

Putting on something new requires an adjustment, but over time we grow into it, and it suits us better. We may even see things we didn’t see before. In Romans 13, the apostle Paul instructed Christ followers to “put on the armor of light” (v. 12) and practice right living. They had already believed in Jesus, but it seems they had fallen into “slumber” and become more complacent; they needed to “wake up” and take action, behave decently and let go of all sin (vv. 11-13). Paul encouraged them to be clothed with Jesus and become more like Him in their thoughts and deeds (v. 14).

We don’t begin to reflect the loving, gentle, kind, grace-filled, and faithful ways of Jesus overnight. It’s a long process of choosing to “put on the armor of light” every day, even when we don’t want to because it’s uncomfortable. Over time, He changes us for the better.
