Those who live according to the sinful nature have their minds set on what that nature desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires. The mind of sinful man is death, but the mind controlled by the Spirit is life and peace; the sinful mind is hostile to God. It does not submit to God's law, nor can it do so. Those controlled by the sinful nature cannot please God.
You, however, are controlled not by the sinful nature but by the Spirit, if the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, he does not belong to Christ. But if Christ is in you, your body is dead because of sin, yet your spirit is alive because of righteousness. And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies through his Spirit, who lives in you.
Therefore, brothers, we have an obligation—but it is not to the sinful nature, to live according to it. For if you live according to the sinful nature, you will die; but if by the Spirit you put to death the misdeeds of the body, you will live, because those who are led by the Spirit of God are sons of God…
Not about ADDING the Spirit into our already busy life
“The Spirit who raised Christ from the dead is not someone we can just call on when we want a little extra power in our lives. Jesus Christ did not die in order to follow us. He died and rose again so that we could forget everything else and follow Him to the cross, to true Life. ( Forgotten God , 122).
Now as He was going out on the road, one came running, knelt before Him, and asked Him, “Good Teacher, what shall I do that I may inherit eternal life?” So Jesus said to him, “Why do you call Me good? No one is good but One, that is, God. You know the commandments: ‘Do not commit adultery,’ ‘Do not murder,’ ‘Do not steal,’ ‘Do not bear false witness,’ ‘Do not defraud,’ ‘Honor your father and your mother.’ ”[ c ] And he answered and said to Him, “Teacher, all these things I have kept from my youth.” Then Jesus, looking at him, loved him, and said to him, “One thing you lack: Go your way, sell whatever you have and give to the poor, and you will have treasure in heaven; and come, take up the cross, and follow Me.” 22 But he was sad at this word, and went away sorrowful, for he had great possessions.
Question: Which is more frightening – giving up everything you own or going through life without the Holy Spirit?
