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 and I will put my spirit within you, and
cause you to walk in my statutes, and ye shall keep my judgments, and do them.
Jer 31:33-34,
But this shall be the covenant that I will make with the house of Israel; After those days, says the LORD,
I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people and they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, says the LORD: for I will forgive their iniquity, and I will remember their sin no more.
Heb 8:10-12,
For this is the covenant that I will make with the house of Israel after those days, says the Lord;
I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people and they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest. For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more.
So now under the new covenant when God changes our heart; we will love God and our neighbour.
if we love God we will not steal
if we love God we will not murder
if we love God we will not commit adultery
if we love God we will not lie
if we love God we will honour our parents
if we love God we will not covet
if we love God we will have no other gods except our God who loves us
if we love God we will not make unto any idols
if we love God we will not take the name of the LORD thy God in vain
if we love God we will Remember the Sabbath day, to keep it holy as he asked us to!
God’s Law has always been central to both the Old and the New Covenant. It is only by the operation of God as we have Faith in His Word that God changes our hearts so that we can love him and love our neighbour that we can walk in his ways. This is why Jesus says its only if you love me we can keep hid commandments (
John 14:15)
