Do you realize how vague and inexact that is ?
What is the minimum ?
What frequency of sin is permissible ?
What is "serious" sin ? Do David's sin qualify ? Samson's ?
How serious was the sin of the priest and the Levite ... who walked past the injured man on the road to Jericho ?
According to the scriptures, God made it very plain. Sin ... is
missing the mark ... of God's calling to perfection. Sin ... is the violation ... of God's Law.

Matthew 22
34 And when the Pharisees heard that Jesus had silenced the Sadducees, they themselves gathered together.

38 This is the first and greatest commandment.
39 And the second is like it: ‘Love your neighbor as yourself.’

James 2:10 For whoever shall keep the whole law, and yet stumble in one
point, he is guilty of all.
So ... you see, the Holy Spirit is not given to perfect little angels. The Holy Spirit is bestowed to dirty little street urchins, BORN into the kingdom of God, ... but still learning and growing, ... until we reach the full measure of Christ. In effect, it is the job of the Holy Spirit to raise us up from our dirt ... and that requires getting One's hands a little dirty ....
