One sort of Christian believes taking Eucharist weekly saves her. Another Christian believes his confession of Jesus Christ as Lord saves him. Still another looks to his Baptism. Another to her participation in the body of Christ. One to his repentance. And another to her care for the sick, the hungry, the prisoner, and the poor.
We elevate one belief or practice over another, then divide ourselves as Christ followers by the priority we set when, in fact, all of these are taught as saving by Christ, who alone is our salvation.
Christ saves me, not the accuracy and purity of my beliefs. Christ saves me, not my works. Christ saves me, not the measure of my adherence to a doctrine or practice.
When all is said and done, many Christians tend to look to their habits, their faith, and their perseverance when it comes to salvation rather than to the work, belief, and faithfulness of Christ in us, over us, under us, and through us.
