Communion is a good old Puritan word that means hanging out with God. Spending time with him. Getting to know him. Abiding in his word. Meditating on it. Talking with Jesus – thanking him, praying, casting our cares on him.
The peace Jesus is talking about isn’t world peace, inner peace, or even peace between people (though this peace leads to peace between people). He’s talking about the peace with God he bought on the cross.
Why does God give us this command? Isn’t it enough to be morally pure? Isn’t it enough not to curse and punch holes in the wall when required to do something unpleasant? What’s so bad about complaining or grumbling a little bit? Everybody does it.
God is the great artist who produces the ultimate masterpieces – sons and daughters in the likeness of his Son Jesus Christ. So he makes every stroke of the Master’s brush, every tap of the Sculptor’s chisel count.
We may “crave” to grow spiritually, but it won’t happen without diligent effort. It is the diligent person – the one who keeps on plodding day after day, faithfully reading her Bible, praying, fellowshipping, listening to messages – who will have her soul richly supplied.
