The "fruit of the Spirit: is the spontaneous work of the Holy Spirit in us. They are the by-products of Christ's control, & we can't obtain them by trying to get them. If we want the fruit of the Spirit to grow in us, we must join our lives to his. We must know him, love him, remember him, imitate him.
A person who is rich in the fruit of the Spirit fulfills the Law for better than a person who observes the rituals but has little love in his heart.
In order to accept Christ as Saviour, we need to turn from our sins & willingly nail our natural evil desires to the cross. As Christians we still have the capacity to sin, but we have been set free from sin's power over us & no longer have to give in to it. We must daily commit our sinful tendencies to God's control, daily crucify them, & moment by moment draw on the Spirit's power to overcome them.
As we live by the Holy Spirit's power, we need to submit every aspect of our lives to God - emotional, physical, social, intellectual, vocational. The Holy Spirit is the source of your new life, so walk with him.
Those who look to God for approval won't need to seek it from others.
