How can tomorrow affect today?

What an intriguing prompt from Queen Creative!

Time and time travel are topics, which have inspired many writers.  In my teens I used to walk to the main library in the town where I lived in order to borrow books by my favourite authors.  Two of them were H. G. Wells and C. S. Lewis.  I am still amazed by H. G. Wells writing.  He lived from 1866 to 1946.  Advances in science and technology were already advancing faster than ever before, but his stories strike me as visionary.  C. S. Lewis (1898 – 1963) was a professor of English, who also wrote about Christianity.  His science fiction trilogy (Out of the Silent Planet, Perelandra and That Hideous Strength) is rather less famous than the Narnia books and his theological works.

Those were some of the early influences on my thinking.

Time is an interesting concept.  We measure it by the way night and day follow each other.  The Bible tells us that God’s concept of time is different to ours.  (He is in heaven and we are on earth.)

The calendar, which is most widely used on earth is in two sections.  B. C. describes the period before Jesus was born.  Before Christ.  A. D. describes everything afterwards.  I have noticed that A. D. is being replaced by a new abbreviation.  Anno Domini means the year of the Lord.  People who do not acknowledge the lordship of Christ are now calling the age we live in CE, which is variously rendered as Common Era, Current Era or Christian Era.

The fact is that the Incarnation, Life, Death, Resurrection and Ascension of Jesus Christ changed the way events in history are recorded.

It can be argued that what He will do in the future affects the past and the present.  The Bible tells us that He will return to earth.  Acts 1:1-11

He warned his disciples to watch for his return and to be ready for it.  Matthew 24:1-51

So coming back to the prompt about Retrocausality.

Promises are about what is going to happen in the future.  If children are told that Santa Claus only brings presents to good children, they may behave better in the hope of a reward.  (Why do we teach children this?)  Similarly, Christians who believe the promises in the Bible, will act in ways that others might not.  I am not saying that Christians are superior to those with other beliefs, rather that they, being aware of their failings, are learning to trust in the mercies of God, who strengthens them to become more like Jesus, who made Himself the servant of all.

God keeps his promises.   Hebrews 10:23
