Hardened Not Your Heart

Grafting or graftage as defined by +Wikipedia is a horticultural technique whereby tissues from one plant are inserted into those of another so that the two sets of vascular tissues may join together. This vascular joining is called inosculation. The technique is most commonly used in asexual propagation of commercially grown plants for the horticultural and agricultural trades.

In stem grafting, a common grafting method, a shoot of a selected, desired plant cultivar is grafted onto the stock of another type.

In another common form called bud grafting, a dormant side bud is grafted onto the stem of another stock plant, and when it has inosculated successfully, it is encouraged to grow by pruning off the stem of the stock plant just above the newly grafted bud.

The same method was used by God in grafting the laws to his own people.

Jer 31:33 But this shall be the covenant that I will make with the house of Israel; After those days, saith 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.

Heb 8:10 For this is the covenant that I will make with the house of Israel after those days, saith 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:

For we are all sinners and considered by the Scripture as wild by nature likened to a wild olive-tree but we're given the chance to partake of the bread and to inherit the promise of eternal life.

Rom 11:16  For if the first fruit is holy, the lump is also holy: and if the root is holy, so are the branches.

Rom 11:17  And if some of the branches be broken off, and thou, being a wild olive-tree, art ingrafted among them, and with them partakest of the root and fatness of the olive-tree; 

Rom 11:18  Boast not against the branches. But if thou boastest, thou bearest not the root, but the root thee. 

Rom 11:19  Thou wilt say then, The branches were broken off, that I might be ingrafted. 

Rom 11:20  Well; because of unbelief they were broken off, and thou standest by faith. Be not high-minded, but fear: 

Rom 11:21  For if God spared not the natural branches, take heed lest he also spare not thee.

Rom 11:22  Behold therefore the goodness and severity of God: on them who fell, severity; but towards thee, goodness, if thou shalt continue in his goodness: otherwise thou also shalt be cut off.

Rom 11:23  And they also, if they abide not still in unbelief, shall be ingrafted: for God is able to ingraft them again.

Rom 11:24  For if thou wast cut out of the olive-tree which is wild by nature, and wast ingrafted contrary to nature into a good olive-tree; how much more shall these, which are the natural branches, be grafted into their own olive-tree? 

Don't be too wicked, neither be foolish. Why should you die before your time?

1 Tim 5:6  But she that liveth in pleasure, is dead while she liveth.

Eccles 7:29  Lo, this only have I found, that God hath made man upright; but they have sought out many inventions. 

Why then do we harden our hearts, as the Egyptians and Pharaoh hardened their hearts? As Jesus Christ said to his disciples: Have your heart yet hardened?  

Eph 4:18   being darkened in their understanding, alienated from the life of God, because of the ignorance that is in them, because of the hardening of their hearts;
