“I am the vine, you are the branches; he who abides in Me and I in him, he bears much fruit, for apart from Me you can do nothing. “If anyone does not abide in Me, he is thrown away as a branch and dries up; and they gather them, and cast them into the fire and they are burned. “If you abide in Me, and My words abide in you, ask whatever you wish, and it will be done for you. “My Father is glorified by this, that you bear much fruit, and so prove to be My disciples.” (John 15:5–8 LSB).  https://accordance.bible/link/read/LSB#John_15:5

We are commanded to abide with Jesus, to be with Him, to dwell intimately with Him. Our experience of our relationship with God should be familial and thus growing in familiarity for He has invited us to call Him Father. Like any close relationship, the necessary ingredient for it to work is time. Our time with God in the reading, meditating, listening, and studying of His word is imperative for abiding with God. We cannot be with Him without being in His word consistently, daily, increasingly. We remain in Him as we pray back to Him His Word, asking Him for understanding, power to obey, and effectiveness at application. As we do His word we see the results of His presence in us, fruitfulness, that is the desired outcome of God for our lives. God is committed to our becoming fully like Him in Jesus, this means we should be ever increasing in likeness to His humility, service, love, sacrifice, giving, and speaking of the ways of God to people in order to win them to God in Christ and grow them in Christlikeness even as we ourselves are doing the same. If this fruit of Christlikeness, and the fruit of people coming to Christ through our lives is occurring, then truly we are abiding as we have been commanded. We know we are His when we are with Him consistently and seeing people consistently coming to Him through our words and deeds intentionally drawing people to Jesus. This is the desire of God, that His kingdom come and His will be done on earth as it is in heaven and we who are the branches, attached to Him Who is the vine, are the bearers of that fruit, the fulfillment of God’s desire working out of us the life of Him Who is working in us.
