John 16:16 "A little while, and you will not see Me; and again a little while, and you will see Me, because I go to the Father."
Our Lord went back to the Father after His resurrection so that according to scripture He would be glorified. Only after Jesus was glorified will the Holy Spirit, Who comes as the Helper or Spirit of truth be given by the Father.
John 7:38-39 "He who believes in Me, as the Scripture has said, out of his heart will flow rivers of living water." But this He spoke concerning the Spirit, whom those believing in Him would receive; for the Holy Spirit was not yet given, because Jesus was not yet glorified."
Rom 8:34 Who is he who condemns? It is Christ who died, and furthermore is also risen, who is even at the right hand of God, who also makes intercession for us.
Our Lord Jesus is now at the right hand of the Father and He is interceding for us.
The Holy Bible is the word of God and in it, we find His covenant with us. Whenever we see the word 'If', we will also see 'His promise'. Though God is all sovereign, He is also just and righteous. He must always be faithful to His words and promises because He cannot sin, lie nor deceive.
John 14:15-16 "If you love Me, keep My commandments. And I will pray the Father, and He will give you another Helper, that He may abide with you forever."
So if anyone keeps His commandments, our Lord will pray to the Father to give the Helper to abide in him forever so that the Helper will help this brethren to be transformed into His image and he will never lose His salvation.
Rom 8:27-30 Now He who searches the hearts knows what the mind of the Spirit is, because He makes intercession for the saints according to the will of God. And we know that all things work together for good to those who love God, to those who are the called according to His purpose. For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren. Moreover whom He predestined, these He also called; whom He called, these He also justified; and whom He justified, these He also glorified.
Having searched our hearts (foreknew) and is satisfied that we have kept His commandments because we love Him, then we will be called, for He has predestined that all those who love Him to be called. All those called will also be justified and glorified for the Helper or Spirit of truth will help them to be transformed into His image.
The word of God is perfect and only the wicked, unlearned and those without truth distort and corrupt it. God has given us the right to decide our future. IF we believe and keep His words, then we have eternal life. But IF we reject Him and the truth, then damnation awaits us as promised.
2Pet 3:16 as also in all his epistles, speaking in them of these things, in which are some things hard to understand, which untaught and unstable people twist to their own destruction, as they do also the rest of the Scriptures.
Where are those who teach that the Almighty God is all Sovereign and does not need to keep His covenant? Unfaithful to His words and promises! this is blasphemy.
Brethren, hold fast onto sound doctrine based on the truth in the word of God and beware of doctrines of man which are normally heresies. 'These people draw near to Me with their mouth, and honor Me with their lips, but their heart is far from Me. And in vain they worship Me, teaching as doctrines the commandments of men.' (Mat 15:8-9)
