Romans 6:8 : But if we died with Christ, we believe that we shall also live with him. Paul is not here referring to life with Christ in the world to come. He is stating a present, general truth. "The future tense does not necessitate a reference to the future life, and in the context such a reference is very unnatural; it is rather the logical future tense marking the new life as fulfilling a promise or natural consequence." Note in Cambridge Greek Testament. We died to sin, and were raised to a new life. This new life we live with Christ. We must live with him as our guide, as our Teacher, as our High Priest, and as our King. We cannot, therefore, continue in sin.
