Acts 2:38, Then Peter said to them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins , and ye shall receive the gift of the Holy Ghost.  KJV

Acts 2:38 Then Peter said to them, "Have a new mind, and be baptized every one of you into the Name of Jesus Christ for the release from bondage to, and pardon from sins, and you shall receive the gift of the Holy Ghost."  literal

Entering into forgiveness is instant.  It happens in a moment.  You ask.  God forgives.  The total removal of bondage to sin is progressive.  It is a process.  It always starts by God speaking to you.  Faith comes by hearing. Hearing comes by an utterance (word) of God.  The faith that comes is from God.  Perhaps some may say this is obvious, but so many Christians try to manufacture faith and end up with a weird faith that is a rationalized faith.  The faith that comes from God is a supernatural belief that is God's belief that has been imparted to men and women.  Faith gives access into God's grace, God's free gift.  When God is giving this gift, it is the gift of Himself.  God is love.  Love fulfills the law.  Love is righteousness and righteousness is love.  Love is God.  God gives us of His love that flows through us in righteousness.  The love of God is shed abroad in our hearts by the Holy Ghost.  We can yield to Him or not.  We can choose to try to obey the utterance that we heard (that resulted in faith), we can try to obey in our own power--that is, to try to establish our own righteousness.  On the other hand, we can simply submit to the righteousness that flows from God.  If we do submit, then God does His work though us.  Otherwise, we become self-righteous.  This righteousness that is from God will move us into every precept that God has revealed in Scripture.  

(some caveats about hearing God's Voice)

See, sayeth He, that you build all things according to the pattern. God is speaking to us about the pattern that He has given in Scripture. The foundation of the Church must be laid first. First Christ, then the apostles built on Christ as foundation of the Church. These apostles were restored to the Church in the late 1940s. God has been restoring His Church to its original glory and purpose since it left God's pattern in the early centuries after Jesus ascended and gave gifts to men. May God bless you in this work.

John 3:16 also reflects this concept of entering into the things of God as a process that God does within us.  John 3:16 For God so loved the world, that He gave His unique Son, that whoever believes into Him should not perish, but have the genuine and absolute fullness of life of the Kingdom Age. * (read more)

Where eis is translated as "for" it would sometimes be better translated as "into."

++++  
Not to be confused with 911, bapto. The clearest example that shows  
the meaning of baptizo is a text from the Greek poet and physician Nicander, who lived about 200 B.C. It is a recipe for making pickles and is helpful because it uses both words. Nicander says that in order to make a pickle, the vegetable should first be 'dipped' (bapto) into boiling water and then 'baptised' (baptizo) in the vinegar solution. Both verbs concern the immersing of vegetables in a solution. But the first is temporary. The second, the act of baptising the vegetable, produces a permanent change.  
When used in the New Testament, this word more often refers to our union and identification with Christ than to our water baptism. e.g. #Mr 16:16. 'He that believes and is baptised shall be saved'. Christ is saying that mere intellectual assent is not enough. There must be a union with him, a real change, like the vegetable to the pickle!
