Act 9:18 And immediately there fell from his eyes as it had been scales: and he received sight forthwith, and arose, and was baptized.
It does not say Ananias told him arise and be baptized and wash away your sins but he would have to be water baptized to wash away his sins.
There are 2 accounts of Saul’s conversion. One in Acts 9 and another in Acts 22. In Acts 22 Paul is telling his conversion story and he says in verse 16 that Ananias said to him “Arise and be baptized and wash away your sins.”
I do believe water baptism is part of the salvation plan of God, and water baptism is for the washing away of sins.
Jesus said a person must be born of the water and Spirit.
Acts 2:38 says baptism is for the remission of sins.
Jews, Gentiles, and Samaritans were all water baptized, and those that were baptized unto John's baptism had to be baptized again.
Romans says we are buried with Christ by baptism into death, for if we are planted together with Christ in the likeness of His death then we will also be in the likeness of His resurrection.
We are not baptized to be part of the Church, or to show we have faith, but we are baptized to identify with the man Christ Jesus in His death.
We have to identify in His death, burial, and resurrection, by repenting of our sins, being water baptized to lay down our sins, and to receive the Holy Spirit.
We cannot cut out the middle man, water baptism, for it is part of the salvation plan of God and we have to identify the man Christ Jesus.
The Bible speaks of the flood and how 8 people were saved by water and the like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ.
It is obvious it is speaking of water baptism for it states it is not the putting away of the filth of the flesh which water will do, and it is identified with the flood which is water.
Which it says baptism does now save us.
Some people say we are not saved by works and water baptism is work.
But the Bible says it is the work of faith, and faith works by love.
Faith is work, repentance is a work, for everything we do, and say, and think is a work.
Also they say we are saved by faith alone, but the Bible says charity, love in action, is greater than faith.
Which means no love then no faith because love is greater than faith, and faith works by love.
Which many people that say faith alone violate love because they hold on to sin because they think they cannot fall so they enjoy sin, but love does not think an evil thought, and does not rejoice in iniquity, but rejoices in the truth.
And they go by their wants but Paul said if any person teaches godliness is gain from such withdraw yourselves having food and clothing be content.
For the love of money is the root of all evil for it neglects the poor and needy, and love is the fulfilling of the law.
Which some have a form of godliness but deny the power thereof, ever learning and never able to come to the knowledge of the truth, and are lovers of pleasures more than lovers of God.
So these people will fall short of fully understanding the Bible which many that say faith alone would fall under that which they also say water baptism is not part of God's salvation plan even though the Bible says water baptism does now save us.
