In Old Testament days the new year was recognised by a trumpet blast and a day of rest (modelled on Lev 23:23-25). Originally Ram’s horns were used, probably in time they were replaced by silver trumpets. The trumpet blast was a ‘memorial’ — a reminder of God’s goodness & faithfulness for the year past, also for the year to come. A holy assembly was called (a renewal of covenant obligations to God).
Of course, the modern way of ushering the new year is through parties and fireworks.
But the trumpet blast of Old Testament days has it counterpart in the trumpet call of New Testament days – but this trumpet announces the coming of the Lord, not for a new year, but for the beginning of a new age (1 Thessalonians 4:16).
And so a good new year’s resolution is to be ready for him. Christians now listen for the trumpet call which will announce the end of the age when the Messiah will come to judge the word and establish his reign.
And now, dear children, remain in fellowship with Christ so that when he returns, you will be full of courage and not shrink back from him in shame …… Dear friends, we are already God’s children, but he has not yet shown us what we will be like when Christ appears. But we do know that we will be like him, for we will see him as he really is. And all who have this eager expectation will keep themselves pure, just as he is pure. 1 John 2:28 and 3:2-3.
