There is the progressive work of sanctification which begins when you are saved. On your part, this is called total commitment or consecration. It is an absolute requirement. Only after you have been made alive can you commit that life to God. The Scriptures teach that the evidence of the fullness of the Holy Spirit is fruit, not gifts.
Sin is always a possibility.
A Christian does not continue the habit and practice of willful sin. He then answered his own question. Be sure your past sins are confess and forgiven, and that you are walking in obedience to the light of God s word. Recognize that you need to be sanctified, that it is God s will for your life, and that He is waiting to do it now. Commit every area of your life to the will of God.
