At first sight, this almost fills us with dismay: the exhortation, ‘Be ye therefore followers of God, as dear children.’ Imitators of Paul, followers of Paul? Yes! – the apostle urges that in four other places and that is feasible for us, since Paul is but a man – but to be commanded to be followers of God, surely that is impossible.
Kindness starts at home: kindness to husband, kindness to wife. Note the word here ‘walk’. God does not want just a few spurts of kindness, but a steady walk every day throughout life. To be kind is costly. It is hard to be kind when the other party is unreasonable, or unappreciative. It doesn't matter. By this means you are imitating in some degree the very Saviour to whom you owe, everything.
What are the impediments to kindness? They are many: self-love and pride – preoccupation with my way, my comforts, what redounds to my credit, my ease; critical spirit – we see unworthy conduct everywhere and we are hostile to it, but we don’t know how to restrain it and switch the spotlight on ourselves; ill temper – we develop a simmering ill-will and anger is not restrained and put in proportion; indifference and failure to notice other people's trials and pains and needs; the tendency to harbour blame or disapproval. These are some of the things to watch which elbow and force out any motive to be kind.
Kindness is a matter of heart. Spurgeon used an illustration once in Lectures to my Students about people that they had at the church, who didn't last very long. He singled out in his mind an example: a person who soon grew tired of them and went over to the Brethren. And he soon grew tired of the Brethren, and he went over to the Methodists. And he soon grew tired of the Methodists, and he went to a hyper-Calvinistic group. And he soon grew tired of that and he went somewhere else. And in each place he gained a reputation for being very good at argument, arguing some new distinctive set of doctrines or ideas. But in no place did he ever really participate, and Spurgeon's diagnosis was, ‘he had no heart.’ That is what is being referred to here, ‘Walk in love, in kindness.’ Some love the theory – we don't disparage the theory; they love the doctrines – well, that is to be commended. They are good at argument, always talking, always arguing a point, but something you notice is they never participate; you never see them collecting children for Sunday School. Never will this very articulate person offer himself or herself to be a teacher. They never do anything for the Lord. Should you have a workgroup or work party, you never see them there. There is no heart, you see; it is all in the head. They don’t feel for souls, for the Lord, for the work, for people. We are to be people who really appreciate Christ, and are indebted to him, and seek to reflect him.
