Below is a good example of anything that may be considered bad or even evil that is instead entirely different when the intentions are godly--that is to say, from God:
Therefore it is written, that we are to:
2 Corinthians 7:2-12
Open your hearts to us. We have wronged no one, we have corrupted no one, we have cheated no one. 3 I do not say this to condemn; for I have said before that you are in our hearts, to die together and to live together. 4 Great is my boldness of speech toward you, great is my boasting on your behalf. I am filled with comfort. I am exceedingly joyful in all our tribulation.
5 For indeed, when we came to Macedonia, our bodies had no rest, but we were troubled on every side. Outside were conflicts, inside were fears. 6 Nevertheless God, who comforts the downcast, comforted us by the coming of Titus, 7 and not only by his coming, but also by the consolation with which he was comforted in you, when he told us of your earnest desire, your mourning, your zeal for me, so that I rejoiced even more.
8 For even if I made you sorry with my letter, I do not regret it; though I did regret it. For I perceive that the same epistle made you sorry, though only for a while. 9 Now I rejoice, not that you were made sorry, but that your sorrow led to repentance. For you were made sorry in a godly manner, that you might suffer loss from us in nothing. 10 For godly sorrow produces repentance leading to salvation, not to be regretted; but the sorrow of the world produces death. 11 For observe this very thing, that you sorrowed in a godly manner: What diligence it produced in you, what clearing of yourselves, what indignation, what fear, what vehement desire, what zeal, what vindication! In all things you proved yourselves to be clear in this matter. 12 Therefore, although I wrote to you, I did not do it for the sake of him who had done the wrong, nor for the sake of him who suffered wrong, but that our care for you in the sight of God might appear to you.
The same actions without being "godly" (or from God) would be considered harmful. This is also true of many things, even weapons and war. God has purpose in "all things" and...as it is written, "is working all things together for good, for those who love Him according to [His] purpose." In other words, intentions, agendas, and purpose are key, and yet may be completely opposite in affect if not [actually] "according to His purpose." It is for this reason that we should examine ourselves--that is, our intentions, our agendas, and our purpose or reason for what we are doing...in perhaps any and all areas of life, but especially in matters of the church. The point being, that if anything is "our" own intention, agenda, or purpose--it is likely against rather than for God, for we according to God are not good, and if we are it is not we but God who is good within us.Therefore it is written, that we are to:
Examine yourselves as to whether you are in the faith. Test yourselves. Do you not know yourselves, that Jesus Christ is in you?—unless indeed you are disqualified.
