For sure Christ, Jesus is not present with us in a physical form. But He is just as surely Spiritually with the True Saints! No He Spiritually isn't in all as all have not made Him the one and only Master in their Soul Temples! That is what it takes, full and total surrender, not a whit withheld or He cannot take up abode there!
Is not His presence just as real by Spirit as physically? Yes it is and we need to always be in Reverence knowing He dwells within.
So it is when we come to worship Him in Spirit and when it is for a fact in Truth, yes He will be Present in it and in all the true Saints in attendance! We must hold our Reverence to Him very High!
Available to all the true Saints they have the greatest teacher ever available at ALL times and none, not one has any excuse to not know the Truth!
Joh 16:13 Howbeit when he, the Spirit of truth, is come, HE WILL GUIDE YOU INTO ALL TRUTH: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: AND HE WILL SHEW YOU THINGS TO COME.
Now a little from EGW and how the disciples had trouble catching up to this,
"But it was difficult even for the disciples to understand the words of Christ. That Christ should manifest himself to them, and yet be invisible to the world, was a mystery to them. They could not understand the words of Christ in spiritual sense. They were thinking of the outward, visible manifestation. They could not take in the fact that they could have the presence of Christ with them, and yet he be unseen by the world. They had yet to learn that the inward spiritual life, all fragrant with the obedience of love, would give them the spiritual power they needed. {ST, November 18, 1897 par. 6}
"Lord, how is it," questioned one of the disciples, "that thou wilt manifest thyself unto us, and not unto the world? Jesus answered and said unto him, If a man love me, he will keep my words; and my Father will love him, and we will come unto him, and make our abode with him. He that loveth me not keepeth not my sayings; and the word which ye hear is not mine, but the Father's which sent me. These things have I spoken unto you, being yet present with you. But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you." {ST, November 18, 1897 par. 7}
Joh 14:16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; Joh 14:17 Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
1Jo 4:4 ¶ Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world.
