Some you state this as though it is meritorious. “I believe in God” is quite general and thus can be understood in more ways than one. What do you mean you “believe in God?” The standard way to take that is that you believe God exists. Such a claim is all well and good, and while you are close to the truth, it is too basic and not an adequate basis for faith. Your position is deceptive, as it provides a false sense of security. After all, there are myriads of gods in the world.
When John the Baptist appeared as Christ’s forerunner, God’s chosen people had lived under the law of Moses for fifteen hundred years but had not kept it. Hence when John the Baptist appeared his was a call to repentance and water baptism for the remission of sins (Mark 1:4).
John was in earnest, too, for when the thoughtless multitude came to him to be baptized, he sent them back, saying: “Bring forth fruits worthy of repentance” (Luke 3:7-8).
Their lives were to be changed and they were to show it by their “works.”
