The Greek says something like ‘when he was great’, and it may refer – as our translators have, I think, rightly decided – to years, or it may refer to other forms of greatness: great influence, great achievement, great prosperity. Elsewhere, we learn he was now 40 years old.
You and I will probably never be called upon to make a sacrifice anything like as great as that made by Moses, and yet how reluctant we are as Christian people to forsake the world, to forsake our luxuries, our standing, and our position. How reluctant when we are confronted with a decision of some kind either to make our priority the things of God, or the things that serve our material interests. By faith we are called to disavow our one-time position as sons of this world, admirers of its vaunted treasures.
Can it be said of us: ‘When he, when she had come to years’? Have we matured as Christian people? Have we put away childish things? Sometimes even Bible believing churches don't help, they don’t help people to put away childish things. They organise and do childish things, even in worship. The whole thing is childish and entertainment based. Have we come to years? Are we more mature than we were? Have we deepened as people? Have we learned more? Do we know how to help one another and those in distress? Are we those to whom others would naturally turn for advice, for solace, for answers to questions? Sometimes people in their 20s have come to years sooner than people in their 40s and that's a great shame. Can it be said that we are mature that we are people who can be used of God? Can it be said that there is in the right sense of the term a venerability about us, that we have proved the Lord and are not so easily caught out by deceptions and trials.
