Charles Spurgeon Commentary Ezekiel 36:27

"And I will put my Spirit within you, and cause you to walk in my statutes, and ye shall keep mine ordinances, and do them." — Ezekiel 36:27 (ASV)

And I will put my spirit within you,

Not only a new spirit, but my Spirit. God himself shall come and dwell in those hearts which once were a receptacle for the devil.

And I will put my spirit within you, and cause you to walk in my statutes, and you shall keep my judgments, and do them.

Here is sanctification: here is final perseverance. Blessed promises of the covenant of grace.
