How can the Christian Distinguish Right Action from Wrong Action?

For you were called to freedom, brothers. Only do not use your freedom as an opportunity for the flesh, but through love serve one another. For the whole law is fulfilled in one word: “You shall love your neighbour as yourself.” But if you bite and devour one another, watch out that you are not consumed by one another.

But I say, walk in the Spirit, and you will not gratify the desires of the flesh. For the desires of the flesh are against the Spirit, and the desires of the Spirit are against the flesh, for these are opposed to each other, to keep you from doing the things you want to do.

But if you are led by the Spirit, you are not under the law. Now the works of the flesh are evident: sexual immorality, impurity, sensuality, idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.

But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law. And those who belong to Christ have crucified the flesh with its passions and desires. If we live by the Spirit, let us also keep in step with the Spirit. Let us not become conceited, provoking one another, envying one another.

From the Letter of Paul to the Galatians.

Do you worry that you fall short of the standard described by Paul? Repent and ask God for forgiveness for your sins, and ask for God to send his Holy Spirit to dwell in you. If you make Christ number one in your life, he will empower you to escape the grip of sin and develop tendencies towards righteousness.
