Morality is in regard to what we ought to do and we ought to be in God's likeness by being a doer of His character traits and His law is His instructions for how to do that. Jesus lived morally and he also lived in sinless obedience to God's law. Likewise, God's character traits are the fruits of the Spirit. Everything in God's law is in regard to how to love Him and our neighbor.
We must be Born Again , ‘tis the Spirit who is at work in our hearts...we are helpless without the Spirit, who is maturing and growing us in our spirit to be more Christ like.
The fruit of the Spirit, comes from the fruit that we bear as we grow in our hearts/ spirit....this is not our fruit, it is the fruit of the Spirit, as he works in our hearts and softens our hearts, we will bear his fruit.
We surrender our will over to the Spirit Of Gods will....it gets easier as we grow in spiritual understanding and maturity.
Has taken many years for me to surrender my will over to Gods will...all part and parcel of growing in the Spirit of Christ.
Edit to add..I can’t love my neighbours as myself, without God’s Spirit softening and working in my heart to do so..The Spirit indwells my spirit/ heart, that is where he has taken up permanent residence.
Hence being Born Of The Spirit...Spirit gives birth to spirit.
