We are to walk in the Spirit  -  Galatians 5:16

This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.

We are to walk in the Spirit, so that we will not fulfill the lust of the flesh. To walk in the Spirit is to allow the Holy Spirit of God to have His way in our life, to remain in close communion with Him, to make decisions in the light of His holiness, and to be focused on Christ. We cannot walk in the Spirit and fulfill the lust of the flesh at the same time, as the one we follow, will be the one which controls our life.
