Grafting is a common horticulture technique. It’s an efficient method of propagation that produces offspring genetically identical to the original plant.
What is grafting?
Grafting typically involves joining together parts of two plants to function as a single plant. One of the plants provides the lower trunk and root system. It’s called the rootstock. (That’s Jesus) The other plant provides the upper portion (stems, leaves, flowers and fruit) that has the desirable characteristics (beautiful flowers or delicious fruit) called the scion.
The rootstock and scion must be closely related and compatible for the graft to be successful. (Jesus said a wild branch could be grafted into Him; that’s us gentiles!)
In general, a wound of some type is made on the stock plant. (Jesus was wounded for us.) A piece of the scion plant is then inserted into the wound.
That means the roots of the stock can provide water and minerals to the scion, and the scion can produce food in its leaves and send it down to the roots of the stock. This creates a functioning plant composed of two genetically different parts.
As in other methods of vegetative or asexual plant propagation, grafting allows us to create exact genetic duplicates of superior individual plants.
If you find a superior pecan tree, for instance, grafting allows the efficient creation of thousands of pecan trees with those exact, superior characteristics. And grafted fruit trees will bloom and produce sooner than those propagated by seeds (which do not produce genetically identical offspring).

Just as a vine’s branches rely on being connected to the trunk from which they receive their energy to bear fruit, Jesus’ disciples depend on being connected to Him for their spiritual life and the ability to bear strong, healthy fruit. The fruit we produce is that of the Holy Spirit—love, joy, peace, longsuffering (patience), gentleness, goodness, faith, meekness (humility), and self-control (Galatians 5:22–23 KJV). Our source of life and spiritual fruit is not in ourselves; it is in Christ Jesus. We can live and serve Him only if we are intimately connected to Him in a faith/love relationship as the above description of grafting describes.
Jesus emphasized His point by saying, “Apart from me you can do nothing” (John 15:5). This illustration of the vine and branches is no thoughtless generality or careless simile. It is absolute, stark reality. No believer can achieve anything of spiritual value independently of Jesus. All true branches bear fruit. Just as we know a healthy, living tree by the good fruit it produces, so do we recognize fruitless branches as having no connection to the True Vine. This is why Jesus tells us, “By their fruit you will know them” (Matthew 7:16–20). Those who do not produce good fruit are cut away and burned.
We depend on Jesus for everything, including our very life—“For in Him we live and move and have our being” (Acts 17:28). No one can truly serve God until he is grafted into Jesus. Jesus is our only connection with the God who gives life and who produces in us the sweet, healthy fruit of love, joy, peace, longsuffering, gentleness, goodness, faith, humility, and self-control which are character traits of the precious Holy Spirit.

I grew up thinking the fruit of the Spirit were character traits of a Christian, so I worked hard at developing each one; but eventually I gave up. I couldn’t develop patience, for example. I did not tolerate fools gladly! Then one day the Light dawned and I understood that those nine characteristics belonged to the Holy Spirit and He wanted to permeate me with His character!! Oh! What a welcome revelation. Being knit with Jesus as my rootstock and being fed from the richness of my dearly Beloved, the fruit I long to bear is sending out buds and tiny shoots. It is amazing that we are commanded in God’s Word to bear fruit and then the way is provided by Jesus being wounded for us to be grafted in – even wild branches can be engrafted. Our part is to surrender all to Him. He gave everything for me. How can I give less than all I have and all I am in return for His sacrifice and pain to buy me back from Satan and restore me to His original plan for my life? Not to mention the deeply satisfying intimacy of knowing Him and being known of Him in ways that challenge description.
