There are things that happen to each and every one of us that make up our days. Our best days and our worst days. If you ask me, these things, of monotony and mediocrity, of misery and mountaintop highs are both turning us into who we will be in five years, yet also revealing who we are right now. So who are you, right now?
Kindness is something that can be shown at any and every stage of life. From our highest highs to our lowest lows. The tenets of Jesus apply to each. True kindness is something that infects. In our fast-paced, throwaway culture, with its shallow mores of interaction, true kindness shown but for a moment will create a pinprick of light in the recipient's day. It's really God shining through us, though we may not realize it at the moment.
"For His merciful kindness is great toward us: and the truth of the Lord endureth for ever. Praise ye the Lord." (Psalm 117:2)
It shouldn't take much to think back and to see the kindness of God's hand in our lives. Y'know, He'll accept any praise or thanks (however small) for anything that we'd like to bring up. It's all present with Him, as it should be with us. We are a product of the infinite kindnesses of the Lord.
"Charity suffereth long, and is kind..." (1 Corinthians 13:4)
God looks to shine His love and kindness to the very depth of our being. There are moments in my life—times of testing, really—where I begin to think, not that God is unkind, but that He's more-or-less indifferent. As if somehow, I've been moved to the periphery of His will, or attention, or whatever. Sometimes I think it's me, and other times, it would seem that He's the one being mercurial. How shallow. It's these times of mediocrity and misery that God is still just as kind as He's always been. Taking the time to slow down and meditate on this aspect of His character will bear fruid by the Holy Spirit. He'll shine through the fog of seeming indifference and show that, yes, He's always been there. Always smiling, encouraging. And kind.
Even times of discipline are kindness. "For whom the Lord loveth He chasteneth, and scourgeth every son whom He receiveth." (Hebrews 12:6) The daughters of God, too. David saw it thus: "Let the righteous smite me; it shall be a kindness: and let him reprove me; it shall be an excellent oil, which shall not break my head: for yet my prayer also shall be in their calamities." (Psalm 141:5) Those whom God used to steer David in the right direction were in turn helped by the payment in kindness that David showed by praying for them in their time of need.
This is how the Body of Christ is meant to function. The kindness we receive from the Lord is meant to refract through us to the rest of humanity, Christians included.
