The simple answer to this is absolutely! According to the scriptures our salvation is conditional to believing and obeying what God's Word says. Of course when we are babes in Christ and do not know any better, in times of ignorance God winks at until he gives us a knowledge of the truth of His Word at which time he calls us all to believe and follow what His Word says *see James 4:7; Acts of the Apostles 17:30-31. At this point if God gives us a knowledge of the truth of His Word we choose to reject it in unbelief and continue in sin then God holds us accountable for sin *compare Acts of the Apostles 17:30-31 with Hebrews 10:26-31.
So our salvation is conditional to continuing in the faith and believing and following what God's Word says.
IS OUR SALVATION CONDITIONAL?
I believe that God's salvation is conditional on believing and following what God's Word says..

We must do well according to Gods' Word (believe and follow) in order to be accepted...

Consequences for not believing and following...

EXODUS 15:26 And said, “IF” (conditional) you will diligently listen to the voice of the LORD your God, and will do that which is right in his sight, and will give ear to his commandments, and keep all his statutes, I will put none of these diseases on you, which I have brought on the Egyptians: for I am the LORD that heals you.
LEVITICUS 26:3-5 , “IF” (conditional) you walk in my statutes, and keep my commandments, and do them;  THEN I will give you rain in due season, and the land shall yield her increase, and the trees of the field shall yield their fruit. , And your threshing shall reach to the vintage, and the vintage shall reach to the sowing time: and you shall eat your bread to the full, and dwell in your land safely.
LEVITICUS 26:14-18 , But “IF” (conditional)you will not listen to me, and will not do all these commandments;  And “IF” (conditional) you shall despise my statutes, or if your soul abhor my judgments, so that you will not do all my commandments, but that you break my covenant: , I also will do this to you; I will even appoint over you terror, consumption, and the burning ague, that shall consume the eyes, and cause sorrow of heart: and you shall sow your seed in vain, for your enemies shall eat it. , And I will set my face against you, and you shall be slain before your enemies: they that hate you shall reign over you; and you shall flee when none pursues you. , And “IF” (conditional) you will not yet for all this listen to me, then I will punish you seven times more for your sins.
There are too many more to write so may stop here for the Old Testament scriptures and maybe post some more latter.
