Some biblical considerations:
- Spiritual maturity rather than absolute moral perfection is the focus behind texts used to suggest the possibility of eradication of the sinful nature (1 Cor. 2:6; Eph. 4:13; Philip. 3:15; Col. 4:12).
- The flesh unaided by the Spirit is weak (Mt. 26:41).
- Daily purification rather than perfection is likely what Jesus meant in John 13:10.
- Sin is present but it cannot rule in the life of the those born from above (Rom. 6; 1 Jn 1:8-10; 3:9).
- James and Paul explicitly state that perfection is not possible (Philip. 3:12; Jm. 3:2).
