The answer
Baptism does not mean you become a slave of God - God also needs your consent, and so when you get older and commit sin, it is your decision to repent and walk with God, or to be unrepentant and walk without God. When you are baptised as a child, that was according to your mother’s faith, but now that you are older, you can make your own decision - baptism will put you on the way to the Kingdom, but you have the free will to continue and be saved, or to go astray.
