John Owen (1616-1683) a Puritan theologian saw the believer's need for daily cleansing. He wrote, "Go daily to Jesus for cleansing. Hence also is manifest the necessity we have of continual applications to Jesus Christ for cleansing virtue from his Spirit and the sprinkling of his blood on our consciences to purge them from dead works."
There are no perfect Christians here below. Your temptations continue. Your battle with the flesh is reality (Galatians 5:17). Your sanctification is not perfect nor complete in this life. Your growth in holiness continues, but you do sin from time to time. Free from the bondage to sin, you are not yet free from the temptation to sin.
Our Lord Jesus not only cleansed you at the point of conversion, but he graciously continues to cleanse you as you confess your sins (1 John 1:7, 9). Scripture warns us not to claim that we are sinless. If you do, then you only deceive yourself (1 John 1:8, 10). John Owen saw every believer's need for daily cleansing.
Owen recognized the need for daily cleansing from our sins as believers. Not only did he recognize the need, but more importantly, he recognized that cleansing is open daily for all believers. Our conscience witnesses to our need. The blood of Jesus avails for your daily cleansing from all sin.
