Many desires a "Deeper Relationship" with God. But no trying will suffice. There has to be a Deeper Revelation from God Himself. Because when He gives a Deeper Revelation that is also the Creation of the Deeper Relationship.
In the Deeper Relationship there is a Deeper Revelation of who God is and who we are. Without this it is not possible to have more than we experience.
Presently we are in a Disciplined situation by our Father. We have ignored the warning not to strife. And we are mostly given over to an evil spirit of strife keeping us in Baby Life of God. We are in different groups striving against one another. Some are from "Apollos" and some are from "Paul". And to the Babies of God their "leader" with his doctrine and religion is their basis for existence and not God anymore. And their Relationships have suffered as consequences of their disobedience.
1 Cor. 3
1 And I, brethren, could not speak unto you as unto spiritual, but as unto carnal,even as unto babes in Christ.
2 I have fed you with milk, and not with meat: for hitherto ye were not able to bear it, neither yet now are ye able.
3 For ye are yet carnal: for whereas there is among you envying, and strife, and divisions, are ye not carnal, and walk as men?
4 For while one saith, I am of Paul; and another, I am of Apollos; are ye not carnal?
5 Who then is Paul, and who is Apollos, but ministers by whom ye believed, even as the Lord gave to every man?
6 I have planted, Apollos watered; but God gave the increase.
7 So then neither is he that planteth any thing, neither he that watereth; but God that giveth the increase.
In this situation there is no more an "closet" Relationship where God is speaking. Where He is Revealing because when He speaks He speaks as the Creator God creating what He say. In these last days of the Word Jesus He reveals more about the Word Jesus. And when He reveals more it is Creation of more of His Life in His Children. Because they have to grow up. But they mostly stagnated at their first meeting with God where they were born again and have not realized that it was just the first encounter and they have to keep the "encounters" Alive for more Spiritual Growth. We got born again when God spoke the first time to us and likewise we can only grow with more speaking of God to us individually in our "closet"
1 Peter 1
23 Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
1 Peter 2
2 As newborn babes, desire the sincere milk of the word, that ye may grow thereby:
As result of this negligence they are not depending on relgion and doctrine to give growht. But it does not have what it takes.
Mat. 15
8 This people draweth nigh unto me with their mouth, and honoureth me withtheir lips; but their heart is far from me.
9 But in vain they do worship me, teaching for doctrines the commandments of men.
And Baby Life stays. What is witnessed in Jesus between the Son and the Father stay far away. But it was given. But never received.
John 17
18 As thou hast sent me into the world, even so have I also sent them into the world.
19 And for their sakes I sanctify myself, that they also might be sanctified through the truth.
20 Neither pray I for these alone, but for them also which shall believe on me through their word;
21 That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.
22 And the glory which thou gavest me I have given them; that they may be one, even as we are one:
23 I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.
24 Father, I will that they also, whom thou hast given me, be with me where I am; that they may behold my glory, which thou hast given me: for thou lovedst me before the foundation of the world.
25 O righteous Father, the world hath not known thee: but I have known thee, and these have known that thou hast sent me.
26 And I have declared unto them thy name, and will declare it: that the love wherewith thou hast loved me may be in them, and I in them.
