I’d say the fellowship with god is found in discipleship and should be constant goal.
“Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.”
John 8:12
“This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all.
If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:
but if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
If we say that we have no sin, we deceive ourselves, and the truth is not in us.
If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
If we say that we have not sinned, we make him a liar, and his word is not in us.”
1 John 1:5-10 KJV
“Hearken unto me, my people; and give ear unto me, O my nation: for a law shall proceed from me, and I will make my judgment to rest for a light of the people. My righteousness is near; my salvation is gone forth, and mine arms shall judge the people; the isles shall wait upon me, and on mine arm shall they trust.”
Isaiah 51:4-5 KJV
“And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.
But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.”
John 3:19-21 KJV
“For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light: (for the fruit of the Spirit is in all goodness and righteousness and truth) proving what is acceptable unto the Lord. And have no fellowship with the unfruitful works of darkness, but rather reprove them.
For it is a shame even to speak of those things which are done of them in secret. But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light. Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light. See then that ye walk circumspectly, not as fools, but as wise, redeeming the time, because the days are evil. Wherefore be ye not unwise, but understanding what the will of the Lord is.”
Ephesians 5:8-17 KJV
“Jesus answered them, and said, My doctrine is not mine, but his that sent me. If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself.”
John 7:16-17 KJV
“Then said Jesus to those Jews which believed on him, If ye continue in my word, then are ye my disciples indeed; and ye shall know the truth, and the truth shall make you free.”
John 8:31-32 KJV
“Jesus answered, Thou sayest that I am a king. To this end was I born, and for this cause came I into the world, that I should bear witness unto the truth. Every one that is of the truth heareth my voice.”
John 18:37
It’s sort of the whole idea of Christianity that God is always with us so our goal is to constantly walk as if he’s with us and fellowship with him continually
“What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's.”
1 Corinthians 6:19-20 KJV
as we walk in light of the gospel learning from Jesus we are fellowshipping and then as we apply those things to our lives we are walking in that light with him and have a constant fellowship
