According to the Bible, the abilities of a pastor are spiritual gifts:

And He Himself gave some to be . . . pastors (Ephesians 4:11).

A pastor is supernaturally called by God to oversee a group of believers. The pastor is to be the teaching elder. In the New Testament he is also called "shepherd," or "bishop." He is to teach and guide the congregation. Peter wrote:

Shepherd the flock of God which is among you, serving as overseers, not by constraint but willingly, not for dishonest gain but eagerly; not as being lords over those entrusted to you, but being examples to the flock (1 Peter 5:2,3).

Jesus said to His disciples, "Feed My lambs" (John 21:15).

Qualifications

The Apostle Paul wrote some of the qualifications of a pastor.

For a bishop must be blameless, as a steward of God, not self-willed, not quick-tempered, not given to wine, not violent, not greedy for money, but hospitable, a lover of what is good, sober-minded, just, holy, self-controlled, holding fast the faithful word as he has been taught, that he may be able, by sound doctrine, both to exhort and convict those who contradict (Titus 1:7-9).

Simply put, a pastor is to minister to the needs of a group of believers.
