Truth is under attack for it is no longer considered to be absolute within our postmodern society. George Barna reported that only 33 percent of Americans accept the idea of absolute moral truth. Barna’s poll also found that even Christians struggle to accept moral truth as absolute. According to Barna, only 49 percent of those born again believe in absolute moral truth. Postmodernism is stripping away the traditional ideas of truth. Therefore the modern Christian believer is required to accurately understand God’s mission through the study of missiology in order to competently relate God’s message by implementing specific evangelistic methods.
Matthew 28:19-20 is the Great Commission and Christ’s final words while on earth to the church. This mandate illustrates the Lord’s intention for the Body of Christ to go to the utter ends of the world to proclaim the good news. The church is not called to be or characterized as a holy huddle, but rather an evangelistic sending agency. Acts 1:8 declares that church is to be witnesses of Christ. That is to say that the believer is to give testimony to the mighty acts of Christ as a faithful witness. Simply put, Christ followers must tell the world about Jesus for communicating the gospel to every man and woman was God’s idea from the very beginning and ultimately speaks to God’s very nature.
World evangelism was God’s plan from the very beginning as it was revealed to us in the Abrahamic Covenant. God did not choose Israel to simply flex His sovereign power and extend blessing to a favored people. God chose Abraham to be the Father of a special nation in order to bless all of mankind. The book of Genesis reveals how God would specifically accomplish this task. He would elevate a nation for the sole purpose of blessing the world. In Genesis 12 God’s first recorded encounter with Abraham is detailed. During that experience God promised to make Abraham a great and mighty nation. God told Abraham that He would bless him and make his name great. In Genesis 15, God makes it clear that He alone would be responsible in fulfilling the covenant and in chapter 17 indicates that this covenant would be an everlasting one. In Genesis chapters 18 and 22 God reiterates the terms of his promises and the initial outworking is evidenced. Although multiple Old Testament and New Testament text reference the promises sworn by God to Abraham by oath, perhaps Isaiah indicates how God would achieve such purpose. God would preserve the nation of Israel in order to give the world a Savior. Of course Isaiah speaks to the Messianic hope that the Jews were anticipating, but this promise was not for the Jews only; the Messiah was the “light to the Gentiles”. God’s plan was to bless the world through the seed of Abraham by establishing an everlasting covenant.
