Read Psalm 48:14
For this God is our God for ever and ever;
he will be our guide even to the end. (NIV)
There is much debate and even confusion about how God specifically guides us. It is likely that his guidance is not so much in specifics but in the general area of becoming more like Jesus. But there is no doubt he is at work in our lives helping us steer clear of false trails and prompting us to take the right paths.
It is therefore interesting to speculate on what might have been had we taken different decisions or took certain actions in the past. How would our lives have worked out? We can never know. What appeared to be coincidences or random happenings may not have been quite so accidental. Perhaps God was behind the scenes causing us to do this rather than that.
Such speculation might be interesting but ultimately futile. We can only be sure God had his eye on us and knew our future even when we did not. We can only be sure we are where we are now and it is where we are now that we love and honour him. We might have experienced all sorts of alternative histories but we can never know what they look like.
Our God has guided us,in both obvious and mysterious ways,to this point. He will go on doing so. We might have chosen another life story to live,but our present story is the only one we have. We might wonder what might have happened if things turned out differently,but in the end it is best to simply give thanks for what has happened and to live life to the full in the only life story we have.
