“…because to this you were called so that you may inherit a blessing.”
The “this” refers to walking with God, basically. So we were called (“we being anyone who accepts that they are a part of the “we”) to live our lives like Christ so that we may inherit a blessing – that is, salvation. But when we veer and do wrong – do we get disinherited?
This faith vs works question can be answered simply by looking at the prodigal son parable, I realized the other day. (Luke 15:11-32) Prodigal was called to be a good son, as all sons are (or daughters). He wasn’t. But his dad still accepted him. His bitter elder brother – was he a good son then? Maybe. Better? Can’t say. Either way, good or bad, as long as they call their father “father”, they share in the inheritance. Like us. As long as we call God “Father” we inherit the blessing.
The question is: do we deserve it? That’s where the ‘calling’ is relevant – and that’s where our answer to the call is relevant.
