Did God only send Jesus into the places where He would be comfortable? Did Christ send Paul into the same kind of places?
Jesus went exactly where His Father sent Him. Paul went where the Holy Spirit now in Him by the promise of Jesus Christ, where Jesus told the Holy Spirit to send Paul. Also kept them from going where God did not want them to go.
If The Holy Spirit sends a person to such a book store, it is most certainly for a purpose, he may be the only one in the store that is sent to bring the truth to the ones God intends to hear and see. With ears that hear and eyes that see, made possible by God, for this person who is in Christ to reveal by the word of God to those he being sent to.
When the bookstore comes to our suffering for Christ's sake for working there then we know we are in the right place that God has sent us.
2 Corinthians 11:22-27 Are they Hebrews? so am I. Are they Israelites? so am I. Are they the seed of Abraham? so am I. Are they ministers of Christ? (I speak as a fool) I am more; in labours more abundant, in stripes above measure, in prisons more frequent, in deaths oft. Of the Jews five times received I forty stripes save one. Thrice was I beaten with rods, once was I stoned, thrice I suffered shipwreck, a night and a day I have been in the deep; In journeyings often, in perils of waters, in perils of robbers, in perils by mine own countrymen, in perils by the heathen, in perils in the city, in perils in the wilderness, in perils in the sea, in perils among false brethren; In weariness and painfulness, in watchings often, in hunger and thirst, in fastings often, in cold and nakedness.
Rom 6:3 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
Rom 8:17 And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with [him], that we may be also glorified together.
2Ti 2:12 If we suffer, we shall also reign with [him]: if we deny [him], he also will deny us:
This is what we should be concerned about in the book store. Are we doing God's intended works for the kingdom, which Christ said we would do greater works the He. We would have to leave this world to get away from these kind of book stores and all else that is in the world that is against God and His Christ.
1 Corinthians 5:9-11 I wrote unto you in an epistle not to company with fornicators: Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must ye needs go out of the world. But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat.
Let go to work in the leading of the Holy Spirit in the book store and save as many as God has given to Christ, then we are harvesting the ripe fields. Hear ye the Spirit and go if He sends.
In Christ: Phillip
