The question of the choice to do good or to do evil may seem to have an obvious answer.
Anyone in the right frame of mind and the right moral disposition would choose to do good.
Also, if one reaps what he sows, then to do evil will only result in evil being done to oneself.
But in the gospel, when Jesus asked the scribes and Pharisees whether it is against the law on the sabbath to do good, or to do evil, they didn't answer the question.
That is rather surprising as the scribes and Pharisees were considered to be religious people and they, of all people, should know clearly what is the obvious answer.
But it was because their minds were clouded with ulterior motives of trying to find something to use against Jesus that they just can't see the obvious.
Even for ourselves, we know what is good and bad and certainly we want to do good.
But often, we end up doing the bad thing because our minds and our hearts are clouded with ulterior motives and vested interests.
Let us pray for clarity of mind and peace of heart so that we will keep our focus on God and always choose to do good.
