I suppose one could use any Scripture in the course of evangelism - I am not arguing otherwise. For instance, Rev 3:20 can be used to show how Christ calls upon saints to repent as a way of showing His long suffering towards sinful people.
The issue that I do believe is dangerous is using a verse for a good purpose even if the verse does not support the agenda.
Example: Act 8:26 and following is used by some to support the contention that the Church must interpret Scripture; whereas what it demonstrates is that lost people being drawn by God need someone within whom the Holy Spirit lives to explain Truth.
The Word of God should be approached with reverence and respect and fear, as He holds those who teach in strict judgment. Our highest priority is to rightly proclaim and teach what God has said, not to convince men Who He is.
