All throughout the Bible it is shown we have a part to do in all of this, including being baptised by water...
Willing obedience made Naaman whole:
Naaman the Syrian consulted the prophet of God as to how he could be cured of a loathsome disease, the leprosy. He was bidden to go and bathe in Jordan seven times. Why did he not immediately follow the directions of Elisha, the prophet of God? . . . In his mortification and disappointment he became passionate, and in a rage refused to follow the humble course marked out by the prophet of God. "I thought," said he, "he will surely come out to me, and stand, and call on the name of the Lord his God, and strike his hand over the place, and recover the leper. Are not Abana and Pharpar, rivers of Damascus, better than all the waters of Israel? may I not wash in them, and be clean? So he turned and went away in a rage." His servant said: "My father, if the prophet had bid thee do some great thing, wouldest thou not have done it? how much rather then, when he saith to thee, Wash [merely], and be clean?" Yes, this great man considered it beneath his dignity to go to the humble river Jordan, and wash. The rivers he mentioned and desired were beautified by surrounding trees and groves, and idols were placed in these groves. Many flocked to these rivers to worship their idol gods; therefore it would have cost him no humility. But it was following the specified directions of the prophet which would humble his proud and lofty spirit. Willing obedience would bring the desired result. He washed, and was made whole.
March around Jericho:
For six days the host of Israel made the circuit of the city. The seventh day came, and with the first dawn of light, Joshua marshaled the armies of the Lord. Now they were directed to march seven times around Jericho, and at a mighty peal from the trumpets to shout with a loud voice, for God had given them the city.
It was God that commanded them to march around that city but had they not done that and obeyed God's command, would God have given them the city?
The woman touched the garment of Christ and also had faith:
Matthew 9:
19: And Jesus arose, and followed him, and so did his disciples.
20: And, behold, a woman, which was diseased with an issue of blood twelve years, came behind him, and touched the hem of his garment:
21: For she said within herself, If I may but touch his garment, I shall be whole.
22: But Jesus turned him about, and when he saw her, he said, Daughter, be of good comfort; thy faith hath made thee whole. And the woman was made whole from that hour.
Jesus said we needed to be washed or else we have no part with Him:
Jn:13:8: Peter saith unto him, Thou shalt never wash my feet. Jesus answered him, If I wash thee not, thou hast no part with me.
Jesus ordered the man to do something, namely, to go WASH in the pool.. he obeyed:
Jn:9:
7: And said unto him, Go, wash in the pool of Siloam, (which is by interpretation, Sent.) He went his way therefore, and washed, and came seeing.
11: He answered and said, A man that is called Jesus made clay, and anointed mine eyes, and said unto me, Go to the pool of Siloam, and wash: and I went and washed, and I received sight.
15: Then again the Pharisees also asked him how he had received his sight. He said unto them, He put clay upon mine eyes, and I washed, and do see.
