Christ came to this earth as THE BRANCH and fulfilled all righteousness, qualifying to replace Satan and rule as King over all the earth. He proved His worthiness by remaining in full accord with His heavenly Father, and bearing the spiritual fruit that makes redemption and salvation possible.
Likewise, we - whether natural or grafted in (Romans 11:17-24) - are also branches attached to the solid trunk of the tree, Christ. It is only by our abiding in Him - our attachment to Him - our close relationship with Him - that we produce any growth or godly works. As Paul writes in Romans 11:16, "If the root is holy, so are the branches." Our righteousness, works, and holiness come to us only because of our connection to Him.
Jesus says that God, in love, prunes us, chastens us, tries us, so that we become more profitable (see also Hebrews 12:3-11). He will do what He must to make us yield. But if we resist and eventually sever our connection with Him, we are fit only to be burned. God has no use for dead wood.
God wants us to use this connection to His Son to "bear much fruit," just as Jesus Christ did. Doing so proves to Him, to ourselves, and to everyone else that we are true Christians, disciples of His Son, the Branch. By this, we will glorify God and secure our place in His Kingdom.
