1 Peter 2:11 - Holy Spirit Power Conquers Sin.

Abstain from fleshly lusts 1 Pet 2:11 (KJV)

Abstain. Christians are to remain without "spot" or "blemish"
(see on Eph. 5:27) in the midst of a morally degenerate world. They
are to avoid every contact with evil habits and practices. This is
what sets them apart as "strangers" and "pilgrims" in this world.
They stand aloof from its degrading pleasures and devote themselves
to things of the spirit. [SDA Commentary]

The basic commandment in this passage is that the Christian
should abstain from fleshly desires. . . Paul's list of the sins of the
flesh in Gal 5:19-21, includes "immorality, impurity, licentiousness,
idolatry, sorcery, enmity, strife, jealousy, anger, selfishness,
dissension, party spirit, envy, drunkenness, carousing, and the like." There
are far more than bodily sins here. [Barclay Commentary]

In the New Testament, flesh stands for far more than the
physical nature of man. It stands for human nature apart from God; it
means unredeemed human nature; it means life lived without the
standards, the help, the grace and the influence of Christ. Fleshly desires
and sins of the flesh, therefore, include not only the grosser sins
but all that is characteristic of fallen human nature. From these
sins and desires the Christian must abstain. [Barclay Commentary]

We must abstain from sins by the power of the Spirit. [Wiersbe
