I am Christian.
For the branches of the vine there are two, or three, requirements to fulfil. If the branches do not meet these requirements, they will be cut off and thrown into the fire.
Firstly, the branch must be responsible. It must be available to the stem. One must love God with all one’s heart, with one's entire mind and with all one’s power. One must always be open to the sap in the stem. One must be nice.
Secondly, the branch must be reliable. It should be effective as a carrier of the stem. One must love one’s neighbour as oneself. One must give fruit. One must be pretty.
A branch must be nice to be pretty. It is impossible for a branch which is not open to the stem to bear good fruit.
A good tree is distinguished from a bad tree by its fruit. A good tree will give fruit which is fine feed, which provides excellent taste and whose seed is in it. A bad tree, differently, will see if you tolerate the fruit. A bad tree puts itself before the one who is eating the fruit.
Jesus Christ, the Son, is the true vine and true Christians are the branches of the tree. The Father is the husbandman. As the branches of the tree, we should be faithful and we should show faith. We are justified by faith, and by faith alone. A third requirement for the branches might be formulated, namely that we must have faith. We must endure trimming. We must endure chastening.
