can anyone tell me the difference betwen a pastor, bishop, reverned and a preacher?

Question

i have heard them all but never knew what they were

Answer 1

A pastor is a shepherd, and as such is responsible for the oversight of a "flock" or congregation of people. The word bishop is derived from the Greek word "episkopos", and could also be rendered by the word overseer.
An overseer is an "over see-er" - again, one who has the oversight of the spiritual condition of a group of believers. "Reverend" is a man made designation, and has no Biblical origin. A preacher is a proclaimer of God's word.
To summarize, the terms are often overlapping and sometimes interchangeable. They take on different meanings in different settings - for instance in many denominations a bishop is one who has oversight of the pastors of a number of congregations.
Another term you didn't mention, which is Biblical, is an elder. This is the broadest and most general term for someone with a position of seniority and therefore responsibility in a local assembly. All of these terms should really be considered in the context of a local assembly, except perhaps "preacher", which could refer to anyone from an apostle down to a layman.
In Acts 20:28 Paul called together the "elders" of the church of Ephesus, and told them to "shepherd", or "pastor" the church of God, among whom the Holy Spirit had made them "overseers", or bishops. So there we see the terms interrelated.
