If you could have asked Moses who was responsible for the miracle parting of the Red Sea, he would have said God. If you could ask God who was responsible for the miracle parting of the Red Sea, He might say Moses.
There is no difference in final result between God parting the Red Sea 100% on His own, and God choosing to part the Red Sea through a 100% yielded vessel like Moses. The water still divides and the poor Egyptians still drown. God appears to prefer work His Glory through obedient trusting individuals. The Bible says that He searches the world over for individuals in whom He can show Himself strong. This does not make God any less a God nor does it make the individual any more a God. It is simply God choosing to work His will as He sees fit.
Jesus was 100% God but He took on the form of a servant in the Incarnation and walked as a man 100% yielded to God. God the Father was the primary source of the miracles of the Gospels. It was God the Father working through God the Holy Spirit, Who was resident within Jesus (the Incarnated Son of Man), which worked the miracles. There is no end result difference between God directly working a miracle and God working a miracle through a yielded vessel.
Therefore, Jesus answered and was saying to them, “Truly, truly, I say to you, the Son can do nothing of Himself, unless it is something He sees the Father doing; for whatever the Father does, these things the Son also does in like manner.” John 5:19
Now, it is God the Father working through Jesus our Lord, who in turn is working through the agency of the Holy Spirit (Who is resident within us), in working miracles. Again, God chooses to stay behind the scenes and work through others to bring about His will. In all this, God is ultimately doing the work. One yields to God by yielding to His Word and to His Spirit. It is still God Who is all in all and Who does it all. In this dispensation, it the Holy Spirit who is the active agent of God on the earth. He, on behalf of Jesus, ‘confirms the Word with signs following.’
“And behold, I am sending forth the promise (of the Holy Spirit) of My Father upon you; but you are to stay in the city until you are clothed with power from on high.” Luke 24:49
“Truly, truly, I say to you, he who believes in Me, the works that I do, he will do also; and greater works than these he will do; because I go to the Father.” John 14:12
“But when He, the Spirit of truth, comes, He will guide you into all the truth; for He will not speak on His own initiative, but whatever He hears, He will speak; and He will disclose to you what is to come. (14) “He will glorify Me, for He will take of Mine and will disclose it to you. (15) “All things that the Father has are Mine; therefore I said that He takes of Mine and will disclose it to you. John 16:13, 14, 15
Of the 214 instances in the New Testament where the Holy Spirit is mentioned, 51 of those (almost 25%) are in the Book of Acts. It is no coincidence that the book that chronicles the first ‘acts of the apostles’ is filled with mention of the Holy Spirit, the source of all miracles. The Book of Acts is sometimes called The Acts of the Holy Spirit.
The more you are yielded to Him the more it is Him. Paul said it well when he wrote, “I can do all things through Him who strengthens me.” And Jesus Himself said, “…. All things are possible to him who believes.” The more we seek Him and seek His will, the more He and His will are revealed in us and through us.
His will includes the manifestation of power through yielded vessels.
For the kingdom of God is not in word, but in power. 1 Corinthians 4:20
For our gospel came not unto you in word only, but also in power, and in the Holy Ghost 1 Thessalonians 1:5
And my speech and my preaching was not with enticing words of man’s wisdom, but in demonstration of the Spirit and of power: 1 Corinthians 2:4
And (we who) have tasted the good word of God, and the powers of the world to come, Hebrews 6:5
