Question:
What does it mean that “we have crucified the flesh” (Galatians 5:24)?

Answer:
God says that the believer was “crucified with Christ” (Galatians 2:20). This is a fact that we cannot feel or experience, but it is our standing before God because He has identified us with Christ.

“We have crucified the flesh,” is our state before God which should correspond to our standing. Since God says the flesh is crucified, we should reckon (or count) ourselves “to be dead indeed unto sin, but alive unto God…and yield [ourselves] to God” (Romans 6:11, 13).
Since “we live in the Spirit, let us also walk in the Spirit” (Galatians 5:25). We should live by the power of the Spirit according to the position (or standing) we have in Christ. If we live in (are controlled by) the Spirit through the Word, the flesh in us is set aside—it is not the ruling factor.
If we live in the Spirit we will have “no fellowship with the unfruitful works of darkness, but rather reprove them….See then that ye walk circumspectly [carefully], not as fools, but as wise, redeeming the time, because the days are evil. Wherefore be ye not unwise, but understanding what the will of the Lord is. And be not drunk with wine, wherein is excess; but be filled with the Spirit” (Ephesians 5:11, 15-18).
