Does once-saved-always saved give permission to sin?

Doesn't teaching eternal security give license to sin?

Part of the reason for John's first epistle is to refute the false notion that since believers know God spiritually, they can freely sin physically. John shows that life from God cannot be characterized by sin. "Whoever has been begotten of God does not practice sin, because His seed abides in him" (1 John 3:9, JND). Divine life imparted at salvation precludes a life of sin. Paul asked. "Shall we continue in sin, that grace may abound" (Romans 6:1)? He shows that our new standing in Christ (6:1-14), our new service, not to sin but to righteousness (6:15-23), and our new supply of power by the indwelling Spirit (8:1-16) preclude a Christian from living under the power of sin.
