Who Is Saving You?

The following comes from By Grace Alone by Sinclair Ferguson (p.75-76):

Your salvation rests not on what you have done but on what Christ has done.  You, therefore, can be sure of it, no matter how weak the faith by which you hold on to Christ, no matter how strong the attacks and accusations of Satan may be.
Remember that you are not saved by increased levels of holiness, however desirable it is that you should reach them.  Indeed, while we often say that we are “saved by faith” or by “faith in Christ,” as Benjamin B. Warfield shrewdly comments, it is not been faith in Christ that saves us.  It is Christ who saves us – through faith.  Your faith is a poor and crumbling thing, as is your spiritual service.  Jesus Christ alone is qualified and able to save you because of what He has done.  Cling to anything else and you are relying on flotsam and jetsam floating on a perilous sea.  It will bring you down under the waves.  If you should ever experience anything like the satanic attack Bunyan’s Christian endured, you will be lost.  But cling to Christ Jesus and His righteousness, and nothing can sink you.
When you grasp that, you begin to realize why and how it is that you can live in the face of such demonic attacks as these.  You are not pushed back on your own resources or spiritual qualities.  You are able to rest exclusively on what Jesus Christ has done for you.  For what He has done for you is absolutely perfect.
What Christ is doing in you is still incomplete.  But in what Jesus Christ has done for you there is not a single tiny crack that the satanic arrows can penetrate.  Jesus Christ is your shield.

Its A Beautiful Gospel
