Tit 3:5 Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost.
This is when we are first saved,for our righteousness is as filthy rags,our works mean nothing,so we can only have faith,for anything we do apart from Christ will not save us,for without the Spirit there is no regeneration,and renewing of the person.
But after we receive the Spirit we are spiritual,and not fleshy,so it is a different circumstance than when we first were saved,and this is supposed to happen.
1Co 15:33 Be not deceived: evil communications corrupt good manners.
1Co 15:34 Awake to righteousness, and sin not; for some have not the knowledge of God: I speak this to your shame.
Gal 6:3 For if a man think himself to be something, when he is nothing, he deceiveth himself.

Gal 6:6 Let him that is taught in the word communicate unto him that teacheth in all good things.
Gal 6:7 Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.
Gal 6:8 For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting.
Gal 6:9 And let us not be weary in well doing: for in due season we shall reap, if we faint not.
1Jn 3:10 In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.

Mat 6:33 But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you.

Jas 2:21 Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar?
Jas 2:22 Seest thou how faith wrought with his works, and by works was faith made perfect?
Jas 2:24 Ye see then how that by works a man is justified, and not by faith only.
When we first come to Christ it is of faith,and believing,but when we receive the Spirit it is about faith,believing,and actions by the Spirit.
