This active obedience is the basis for our righteousness. According to the Confession of Faith our justification, our acceptance, is a single, legal act of God. God accepts us once and it is irreversible, good for all times. It is an unconditional, eternal acceptance. It does not have to happen over and over again every time we sin.
Justification covers over all past sins, all present sins, and all future sins as well.
Some maintain that we must be re-justified, we must be reaccepted, after every sin we commit. As Scripture makes clear, justification is a once for all time act, never to be repeated. It is not a continuing process. Lots of people don't like asparagus but there is something about asparagus that I consider to be amazing. He plants it once, and it is good for twenty or thirty years.
