"If, however, you are troubled about the power of sin, and about the tendencies of your nature, as you well may be, here is a promise for you. Have faith in it, for it stands in that covenant of grace which is ordered in all things and sure. God, who cannot lie, has said in Ezekiel 36:26:
A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh.
You see, it is all "I will," and "I will." "I will give," and "I will take away." This is the royal style of the King of kings, who is able to accomplish all His will. No word of His shall ever fall to the ground."
