The Reformed tradition has consistently seen the doctrine of perseverance as a natural consequence to predestination. According to Calvinists, since God has drawn the elect to faith in Christ by regenerating their hearts and convincing them of their sins, and thus saving their souls by his own work and power, it naturally follows that they will be kept by the same power to the end. Since God has made satisfaction for the sins of the elect, they can no longer be condemned for them, and through the help of the Holy Spirit, they must necessarily persevere as Christians and in the end be saved. Calvinists believe this is what Peter is teaching in when he says that true believers are "kept by the power of God through faith unto salvation". Outside Calvinist denominations, this doctrine is widely considered to be flawed.
