John 1: 12-13 “But as many as received Him to them gave He the power to become the sons of God, even to those that believe on His name, 13. who were born not of the will of the flesh, nor the will of man, but of God.” In addition to these words it is written in John 3, while Jesus is speaking to Nicodemus, the pharisee, vs.3 “Truly, truly I say to you, unless one is born again he cannot enter the kingdom of God.” … vs. 6. “That which is born of the flesh is flesh, and that which is born the Spirit is spirit.”
This is what we understand to be the introduction into the ‘New Covenant,’ which is all things spiritual in our relationship to God , in contrast with the Law which is all things flesh in our relationship to God. To be born of the Spirit is to have the seed of God in you, which produces not fleshy things, but after its own kind, Spiritual things. This seed then like all seeds planted, has to be fed, watered, and cared for in order to mature and produce its fruit.
Colossians 1.25-29 Paul writes to the church at Colossae, ” Of this church, His body, I was made a minister, according to the stewardship from God bestowed upon me for your benefit, so that I might fully carry out the preaching of the word of God, (Which is much more than just evangelism, but starts there) 26. which is, this this mystery which has been hidden from past ages and generations, but has manifested to His saints, 27. to whom Jehovah willed to make known what is the riches of the glory of this mystery among the Gentiles, which is Christ in you the Hope of Glory. 28. We proclaim Him, admonishing every man, and teaching every man, with all wisdom, so that we may present Him mature, complete in Christ. 29. For this purpose also I labor, striving according to His power which mightily works within me.”
When we accept the truth of God’s salvation for us, which entails confession of sins, repentance of sins, understanding Jesus is LORD, and committing to follow Jesus, we are born again, and have the seed of Jehovah in us. This seed wants to grow and reproduce spiritual results, but like the parable Jesus taught on the Sower, Mark 4:3- 8, some seed fell on rocky ground and some fell among the thorns where the cares of this world choked it and rendered it unproductive. Therefore it is up to us, the believer, who has the very seed of God in us to protect, water, and nurture the seed into maturity, so that it can reproduce. This process of maturing the seed is what Paul was obsessed with, what he labored for. It’s only natural for this to be our desire also, and is accomplished only through diligent study of the Word of God, prayer, and listening to good teachers of the Scripture who have the same desire as Paul.
2 Timothy 2:15 “Study to show yourself approved, be diligent to present yourself approved to Jehovah as a workman who does not need to be ashamed, accurately handling the Scriptures.” (It’s spiritual, not of human origin or desire}
1 Thessalonians 4.9 ” Now as to the love of the brethren, we have no need for anyone to write to you, for you are taught by Jehovah to love one another.” ( It’s a God inspired teaching, man cannot do it)
John 14: 12 “Truly I say to you, he who believes in Me, the work that I do , he will do also, and greater works than these he will do, because I go to the Father. 13. Whatever you ask in My name, that I will do, so that the Father will be glorified in the Son. 14. If you ask anything in My name, I will do it. 15. If you love me, you will keep My commandments.”
2 Peter 1:5 “…In your faith supply, ( in context here the implication is, it has to be up to us alone to add to our faith) moral excellence, knowledge, self control, perseverance, godliness, brotherly kindness, and love.”
All these scriptures represent a goal for us to attain to. It is up to us to desire them. It’s spiritual, and God wants us to get there, to be complete.
