Romans 8:9-11

However, you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. But if anyone does not have the Spirit of Christ, he does not belong to Him. And if Christ is in you, though the body is dead because of sin, yet the spirit is alive because of righteousness. but if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit who indwells you.

Galatians 5:16

But I say, walk by the Spirit, and you will not carry out the desire of the flesh.

2 Corinthians 2:16

For who has known the mind of the Lord, that he should instruct Him? But we have the mind of Christ.
