In 1 Corinthians 13 the apostle Paul spends a lot of time talking about Love - what it is and it isn't, what love does and what it does not.
That passage is often read out at weddings.
Most people are familiar with these verses
4 Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 5 It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. 6 Love does not delight in evil but rejoices with the truth. 7 It always protects, always trusts, always hopes, always perseveres.
8 Love never fails.
While he also mentions faith and hope in this chapter, in the end this is all he has to say about them
And now these three remain: faith, hope and love. But the greatest of these is love.
So, what is faith? It is not synonymous with belief. I think it is more like trust in something intangible. Little children tend to trust their parents instinctively. This is the first stage of faith.
Later in life some of us develop faith in ourselves, in our own capacities and judgment, others place their faith in their acquired wealth. Jesus told a parable about the rich man who spent all of his life accumulating a huge stockpile of grain, hoping to live comfortably for the rest of his life. He built huge granaries and filled them but he died as soon as the work was finished. His faith was misplaced.
Every time I sit in a plane about to take off, or I am about to be given an anaesthetic before an operation, I close my eyes and talk to God for a couple of minutes. I give thanks for my life and express my faith that whatever the outcome, all will be well because I have faith in the goodness of God.
Sometimes I'm not sure what I believe about God; that has changed over the decades and there was a time when I believed that God was purely imaginary. What I do know is that I choose to place my faith in the goodness of something that I don't really understand. This anchors me and gives my existence purpose.
So there you are - my take on what I think and personally experience faith to be.
