The "Church of Christ" teaches that "obeying the Gospel" includes being baptized in water in order to be saved.
If this is true, then how is it that the converts of Acts 10 were saved by faith before and without water baptism?
The Bible says in Acts 5:32 that only those who obey God may receive the Holy Ghost - so what did those in Acts 10 do to obey and receive the Holy Ghost and be saved?

You need to read Acts 11. In verse 4, it is stated that the account of this chapter was in order. In verse 14 it is stated that Peter was going to speak words whereby Cornelius and all his house was to be saved. In verse 15 it was stated that that the Holy Ghost fell on Cornelius and his company as Peter began to speak. If the words Peter spoke was to save Cornelius and the Holy Ghost fell on Cornelius before he heard the words which was to save him, then the Holy Ghost fell on Cornelius before he was saved. And we can see the reason for this by reading Acts 15:7-11--It was God bearing witness in an undeniable way the Gentiles were to be subjects of the Gospel just as the Jews were.

I suggest you read Acts 8:12-19 to find how the 1st century gifts of the Holy Ghost was imparted. It was imparted by the laying on of the apostles' hands. (Acts 8:18) Since we don't have any apostles alive today, the receiving of the Holy Spirit was a first century event designed to reveal and confirm the word of God until such revelation was complete. (Hebrews 2:3-5, I Corinthians 13:8-10)
Of course we are to have the spirit of the Father, the spirit of Christ and the spirit of the Holy Spirit alive in us. But we do that by hearing and obeying the knowledge of the word of God. (II Peter 1:3-4, James 1:22) That is the way the Bible tells us to be partakers of the divine nature.
