Is the force of Kamma like a God for Buddhists?

We know Buddhism doesn't have a creator God like most religions, however there is the law of Kamma, a law we cannot see and also we cannot prove, in other words, a law that requires faith and cannot be measured like gravity or electromagnetism. Once a Theravada senior monk said that: "Buddhists should not say they don't believe in God, because they believe in the laws of nature and Kamma, it works like a God, a higher force, only not a creator God, not a being we pray to" So, Is kamma "like" a god?
