For it is by grace you have been saved, through faith - and this not from yourselves, it is the gift of God - not by works, so that no one can boast. Ephesians 2:8-9
 
We have been saved (past tense) by grace, through faith, but not of ourselves, not our faith!  If not ours, then whose faith has saved us?  We were saved by the faith of Christ!  And, the faith of Christ comes to us as a free gift from God.  If it is a free gift, then we cannot earn for ourselves, or sell to others, what is free.  Attempting to get someone to pay for something they already possess is a bit redundant, and even unethical, yet most of the Christian Church today believes it is commissioned to do just that - "get everybody saved" by convincing them to "buy" into what Jesus did for us on the cross at Calvary.
 
Either Christ accomplished His mission or He failed.  The world was reconciled to God through His crucifixion and there is nothing left to be done - nothing to sell or to buy.  We were and still are reconciled to God, through Christ.  We are now at peace with God.  We are holy in His sight.  We are free from accusation.
 
What then is our ministry and mission?  Our mission is to declare the word of reconciliation.  We cannot reconcile people to God, and they cannot reconcile themselves.  They can only awaken to the fact that they have already been reconciled.
 
Salvation is not a happening; it is an awakening or an accepting.  It is not to be sought after or "bought" with our belief in it, or through our good conduct.  It is an everlasting truth, a finished work, to be uncovered.  Being an unbeliever is not synonymous with being unsaved.  We are all saved. Salvation is not chosen but discovered.  So, our going to church to worship and to learn is about so much more than avoiding hell and arriving safely in heaven.  It is to teach us how to live here and now!  Christ did not come to get us to heaven.  He came to get heaven to us!
