James 4:17 If anyone, then, knows the good they ought to do and doesn’t do it, it is sin for them.
Have you ever said you were going to do something and never got round to it?
How many times have you boasted of doing something and never actually done it?
God wants us to be good and faithful people – He also wants us to do what we say we are going to do, otherwise we are nothing but empty vessels!
