It is a common salvation—common because we are all saved by the same Saviour. We are not, some of us, looking to Jesus and others to Moses, or to ourselves. Neither are we, some of us, looking to the atoning death and others to the perfect life of Christ—but we are all saved by the same one work, life, death, resurrection, and intercession of Christ Jesus. When he made atonement by blood, it was for all his redeemed. When he rose, it was to justify all who are in him. When he stands at the right hand of God to plead, he intercedes for all the saints. And when he comes, it will be that all his saints may be with him where he is and may behold his glory.1
Charles H. Spurgeon
3 Beloved, although I was very eager to write to you about our common salvation, I found it necessary to write appealing to you to contend for the faith that was once for all delivered to the saints.
