Our readings today urge us to be mindful – to think about what we think about, and about what we feel, say and do. We are invited to not simply react instinctively, but to consider how we react. Our thoughts and reactions impact ourselves and others, whether we are mindful or thoughtless, whether we are grateful or thankless, whether we are kind or harmful. We are urged to be grateful and kind.

In John 6:41-51, the people who had just had the blessing of being part of the Jesus’ feeding of the 5,000 (men, plus women and children) with fish and bread. You’d think they’d be grateful, but no, they were not. And then Jesus counsels them to not settle for bread that goes stale and moldy, but rather to seek after the Bread from heaven, that never spoils, but endures to eternal life (6:27). He even shares with them that God has sent him as the true bread from heaven and that he gives life to the world.

Still, they grumble and mutter. They remember him growing up in his family and cannot imagine that he could be the bread from heaven. “How can he now say, ‘I came down from heaven?'” Thankless they are! And Jesus chastises them: “Stop grumbling among yourselves!” One senses Jesus’ growing frustration, not only with how earth-bound they are (bread is more valuable to them than God the Son), but also with their unwillingness to see him for who he is.

And so he repeats “Very truly I tell you, the one who believes has eternal life.” And, “I am the bread of life.” And, “Your ancestors ate the manna in the wilderness, yet they died.” And, “But here is the bread that comes down from heaven, which anyone may eat and not die.” How much clearer can he be! You can hear his exasperation with these ungrateful and close-minded people. And so he repeats, “I am the living bread that came down from heaven. Whoever eats this bread will live forever.” And in case they still don’t get it (which they don’t!), he concludes, “This bread is my flesh! I will give it for the life of the world!”

And how do they respond? They “began to argue sharply among themselves.” Eish, the frustration of Jesus that we should be so mindless and so thankless. Here he is, offering us eternal life, right in our midst, and all we do is grumble, moan and argue.

Jesus calls us to a spirit of gratitude – to be grateful that the bread from heaven has come down into our midst, and to cast aside regular bread and instead feast on this heavenly bread that leads us to eternal life.

Paul, in the closing verses of Ephesians 4, similarly calls the Ephesians (whom he profoundly blessed in Ephesians 1 – you can catch my sermon on that here) to be kind to one another. Having been blessed with God’s greatest and most enduring and satisfying gifts (much as Jesus does in John 6), Paul calls us to be kind and considerate to each other. He calls us to set aside falsehood, anger, theft, laziness, unwholesome talk, grieving the Holy Spirit, bitterness, rage, anger, brawling, slander and malice. It’s quite a list!

And instead, Paul calls us to speak truthfully, not to let the sun go down without resolving our anger, to work, to do something useful, to share with those in need, to speak helpful words, to build other up according to their needs, to be kind, to be compassionate, to forgive others, to live a life of love, to follow God’s example.

Paul calls us to be kind – to be considerate, thoughtful, sensitive and helpful to other people, in just the same way that Jesus is with us – since Jesus loved us and gave himself up for us as a fragrant offering and sacrifice to God.

This message – be grateful, be kind – may seem twee and insincere and lefty. But it is core to Jesus’ message, and therefore core to the message of apostles, like Paul, and therefore core to my message as a pastor today, and should therefore be core to how you live your own life.

Of course, we fail. Some of you will have experience me being ungrateful and unkind. I and we can do better. Thankfully, though, we have a God who knows that we fail, and who has already been kind, loving and forgiving of us. We simply come back to him, say we’re sorry, ask for forgiveness, and pray for strength and grace to do better: to be grateful and to be kind. Amen.
