Not one true believer whom the flesh does not again and again incite to impatience, anger, pride. But it is one thing to be tempted by the flesh, and another thing to yield to the flesh, to do its bidding without fear or remorse, and to continue in sin.

Context

“There were many hypocrites among the Galatians, as there are also among us, who pretend to be Christians and talk much about the Spirit, but they walk not according to the Spirit; rather according to the flesh. Paul is out to show them that they are not as holy as they like to have others think they are.
Every period of life has its own peculiar temptations. Not one true believer whom the flesh does not again and again incite to impatience, anger, pride. But it is one thing to be tempted by the flesh, and another thing to yield to the flesh, to do its bidding without fear or remorse, and to continue in sin. Christians also fall and perform the lusts of the flesh. David fell horribly into adultery. Peter also fell grievously when he denied Christ. However great these sins were, they were not committed to spite God, but from weakness.” source
