If his grace is sufficient for you,
No "if".
2 Corinthians 12:9 KJV
(9) And he said unto me,
My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me.
If you're born of God, then you'll have the fruits of the spirit.
Spirit in contrast to
flesh.
Romans 7:18-25 KJV
(18) For
I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
(19) For the good that I would I do not: but the evil which I would not, that I do.
(20) Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
(21) I find then a law, that, when I would do good, evil is present with me.
(22) For I delight in the law of God
after the inward man:
(23) But I see another law in my members, warring against
the law of my mind, and bringing me into captivity to
the law of sin which is in my members.
(24) O wretched man that I am! who shall deliver me from the body of this death?
(25) I thank God through Jesus Christ our Lord. So then
with the mind I myself serve the law of God; but with the flesh the law of sin.
Romans 8:8 KJV
(8) So then they that are in the flesh cannot please God.
