God cannot lie or else He is not truth and therefore He is not divine.
God therefore always tells the truth.
If God promises something, He will fulfill His promise.
With this in mind, I offer this passage for reflection:
"'Thus says the Lord GOD: I will gather you from the peoples, and assemble you out of the countries where you have been scattered, and I will give you the land of Israel.' And when they come there, they will remove from it all its detestable things and all its abominations. And I will give them one heart, and put a new spirit within them; I will take the stony heart out of their flesh and give them a heart of flesh, that they may walk in my statutes and keep my ordinances and obey them; and they shall be my people, and I will be their God." - Ezekiel 11:17-20While meditating on this passage yesterday, I noticed one word jump out at me - "flesh".
God gives us a "heart of flesh" in place of our stony heart. If we have turned our hearts into stone by our sin, then God promises to give us hearts of flesh (another translation says "natural hearts") to replace our stony hearts. We need this, because without a heart of flesh, we cannot live spiritually with God. Of course, this analogy isn't meant to be a treatise on our bodies - rather, the heart signifies the core of the human being.
We must be transformed by God, in order to be made capable of being with Him forever.
But, how does God transform us? Through God taking on a heart of flesh; through Jesus becoming a man. God takes on flesh in order to transform our heart of stone into natural ones, which share the same human nature with Christ.
Transformation of our hearts is difficult, because it requires us to be open to God's love penetrating the depths of our being.
Of course any open heart surgery requires some risk and possibly even death. But, with God as the surgeon, we can know that even though we die, we will rise. Even though it might hurt, we will be healed. Even though we might be scared, God will always fulfill His promises.
He has to. He is God.
God, please make our heart of stone into heart of flesh!
