据说，这篇激发人心的诗篇，是犹太的朝圣者前往耶路撒冷过节时，在路上最常咏唱的一篇诗。这类的诗篇有不少，其中包括有诗篇一二零和一三四篇。它们都写于不同的历史时期，但后来都被汇集为颂赞和歌颂之诗，在百姓聚集的时候一同歌唱。

这篇诗提醒我们，归根究底，只有神才是我们的真正保障。耶路撒冷纵然被群山环绕，却不能保证它的安稳。真正的保护是来自神自己，因为惟独祂才有能力看守着它。而且，这位神亦正是我们众人的神，祂的眼目经常看顾着祂的儿女。祂仿佛紧握着我们的手，拖带着我们走过人生的路途。

正如小孩子有时不喜欢父母拖着他的手，也不喜欢父母看管着他或给予严厉的管教；成年人也是一样，有时不愿意凡事征求神的同意。

当我们出现这种不情愿的情绪时，也许，我们应该先停下来反省一下，我们所相信的，究竟是一位怎样的神。经过反复细想之后，我们将不得不承认，只有神的看顾是最无微不至的。

当我们还未能够看清前路的时候，神早已一目了然。祂知道我们何时会遇上无力承担的困难。祂绝不容许我们遇见那些能力不胜的试探。无论我们身在哪里，是在家中还是路上，祂都必然看顾着我们；我们可以信靠祂的保护，因为祂是恒久不变的神。

这是千真万确的保证，我们为何不更多地信靠祂呢？为何还有怀疑和不信呢？为何不立即就向祂说：「父啊，我愿信靠你，求你加添我的信心，让我懂得时刻信靠你。」

This lovely Psalm is said to have been one of the songs used by pilgrims on their way up to the city of Jerusalem for Jewish festivals. There are a number of these songs (Psalm 120 to Psalm 134). They were written at different periods of Jewish history, but put together as hymns of praise and job, and then sung by the marching companies.

Psalm 121 reminds us that God, and no-one else, is our final refuge. The hills around Jerusalem do not guarantee its safety. It is God himself who does. But he not only watches over the city. He is a personal God whose eyes are always watching over his children. It is as though he holds their hands as they walk along life's pathway.

Sometimes a child doesn't like his father holding his hand. Sometimes children don't like parents being too watchful or strict. Often adults don't like the idea of asking God if they can do certain things or not.

Stop to think of who our God really is. Then you can only admit that if anyone could ever take care of you, he can.

He can see what is ahead if us. He can see when situations would prove too much for us. He will not allow any temptation to touch us that would be too great for us. He watches over us when we go out and when we are at home. He will always do this for us, because he is the Eternal God and never changes.

That certainly is reassuring. Why don't we trust him more? Why do we doubt him? Why not say to him today, 'Father I trust you; just help me trust you always'.
