While it is true we all sin in word thought and deed each day this is why the model prayer tells to confess daily.One who lives in open rebellion against God is not going to enter the kingdom of God as per 1 Corinthian ch 6.Only those that have repented of their sin and as scripture tells us If any man would come after me let him deny himself take up his cross and follow me, only those that have done so will enter the kingdom of heaven.
