This week, our guest speaker, Andrew Porter looks at a Psalm that was written by a man called Asaph. In the Psalm, we see a man who struggles deeply with the temptations all around him and yet seeks to maintain a close walk with the Lord. Highly relevant for the world in which we live today. Many of us will be able to identify with Asaph's struggles as he seeks to honour the Lord, maintain his purity and be an effective witness to those around him.
