The First Helvetic Confession (1536) contains an introduction written for the Lutherans by Heinrich Bullinger:
Although the Lord has expressly said, “No one can come to me unless the Father who sent me draws him” (John 6:44), yet it was his will that the gospel of the kingdom should be preached to all nations and that bishops [pastors] should discharge this duty of the ministry, with great care and diligence, and with special watchfulness, and be instant in season and out of season, and by all means, that they might gain as many as possible unto Christ. For therefore, when he was ready to depart hence into heaven in his body, he said to his disciples, “Go into all the world and proclaim the gospel to the whole creation” (Mark 16:15)
The Second Helvetic Confession (1566) was written by Bullinger. The first chapter is about preaching, in which Bullinger stated that “the preaching of the Word of God is the Word of God.”
He shared that the Holy Spirit uses Scripture to bring light to the dark heart of all men and nations: “For he that illuminates inwardly by giving men the Holy Spirit, the same one, by way of commandment, said unto his disciples, ‘Go into all the world, and preach the gospel to the whole creation’ (Mark 16:15).”
Scottish Confession of Faith (1560) says in article 18 that the first mark of a faithful church is “the true preaching of the Word of God.” The proof text is Matthew 28:19-20 – “The Great Commission”.
The Belgic Confession (1561) has a similar statement and also uses Matthew 28:18-20 as the proof text.
Heidelberg Catechism (1563) asks in QA 32, “Why are you called a Christian?” Answer: “Because I am a member of Christ by faith and thus share in his anointing…”
Christ was anointed with the Holy Spirit to be a prophet, priest, physician/healer, prince and coming king, and so have Christians. We have the same Holy Spirit living in us giving us the same calling as our head Jesus Christ. If we are Christians, then we are prophets (one through whom God speaks). We then need to be witness to Jesus Christ to whomever we can with our lives and words.

What do we pray for in the second petition?
A. In the second petition (which is, Thy kingdom come), acknowledging ourselves and all mankind to be by nature under the dominion of sin and Satan, we pray, that the kingdom of sin and Satan may be destroyed, the gospel propagated throughout the world, the Jews called, the fullness of the Gentiles brought in…
The 1689 London Baptist Confession of Faith establishes personal evangelism as a duty, linking it to the sovereign decree of God to use means (preaching) to call the elect. It does not include a specific chapter on “Evangelism” but Chapter 20 paragraph 3 states “…in all ages, the preaching of the gospel has been granted unto persons and nations”

The 2000 (Southern) Baptist Faith and Message, XI. Evangelism and Missions
It is the duty and privilege of every follower of Christ and of every church of the Lord Jesus Christ to endeavor to make disciples of all nations. The new birth of man’s spirit by God’s Holy Spirit means the birth of love for others. Missionary effort on the part of all rests thus upon a spiritual necessity of the regenerate life, and is expressly and repeatedly commanded in the teachings of Christ. The Lord Jesus Christ has commanded the preaching of the gospel to all nations. It is the duty of every child of God to seek constantly to win the lost to Christ by verbal witness undergirded by a Christian lifestyle, and by other methods in harmony with the gospel of Christ.

Got Questions on personal evangelism
https://www.gotquestions.org/personal-evangelism.html
We are each evangelists, sharing the Good News with anyone (1 Peter 3:15), starting with our family (Mark 5:19), neighbors (John 4:39), co-workers and our “sphere of influence”, usually within our own culture or community. We do so under the authority of and accountability to our local church.
Deacon Philip (chosen in Acts 6) WENT and preached the Good News in Samaria (Acts 8:4-8), led to the conversion of Simon Magus (Acts 8:9-13), and the Ethiopian eunuch (on the road to Gaza - Acts 8:26-39), and preached in Azotus (Ashod) and surrounding towns (Acts 8:40), and was referred to as “the evangelist” (Acts 21:8).
A missionary (“set aside” and a “sent one” by the Holy Spirit – Acts 13:2-3) is considered today as one who crosses national or tribal boundaries (Acts 1:8) and usually engages in long-term work and church planting, which requires learning the culture and language of a specific people group

A missionary may be sent and under the authority of one church, a collaboration of churches (Southern Baptist International Missions Board), or a sponsoring parachurch missions agency. Parachurch international ministries usually have a specific focus ie. operating a hospital or drilling wells for fresh water.
