That means a person who is a Christian has been made into something entirely new. Christians reborn of the Spirit take on a new image within that of God our creator. Their life is to exhibit this new internal spiritual reality. We should not, however, think that this means Christians do not sin. Yes, we are suddenly changed or transformed, in the sense that we have been reborn by receiving the Holy Spirit.
Christians still stumble and sin.
But they don t habitually practice sin. They must continue to be forgiven and purified by Christ. Thus, spiritual renewal is a continuing process throughout the Christian life. We become more Christlike as we live according to God s will. We, like Paul, must be willing to die daily to sin and yield to God s will in repentance.
