Colossians 1.28 explains, we tell others about Christ, warning everyone and teaching everyone with all the wisdom God has given us. We want to present them to God, perfect in their relationship to Christ.
This verse most succinctly defines the occupation or purpose of every Christian: to bring people to Jesus and help them know His will.
When God lived on earth He began His work by inviting men to follow Him so that they could become fishers of men. When God left the earth entrusting His work to the care of men He commanded them to go and make disciples.
The current state of the world is evidence that Christians have been failing miserably in their prescribed occupation. Too much time and attention has been given to our vocation so that we can live more comfortably in a world that is not our true home. The world is in increasingly more desperate need for the Christian message to love God and to love our neighbor.
The world does not need the Muslim message, it is oppressive and vengeful. The world does not need the Hindu message of human separation. The world does not need the Atheist/Agnostic message that provides no basis for morality. The only message that invites love, humility, forgiveness and compassion is the Christian message.
The world suffers because men are evil. It is when men hear the Christian message, turn from their evil ways, and follow God’s commands that real change for the better of all humanity occurs. There is only one God, on that Christians and Muslims agree.
The Christian God, the One True God, commands all people everywhere to turn from their evil ways and to love Him with all their heart, soul, mind and strength. This love is practiced by obedience to His commands. What is His chief command? Love our neighbor as ourselves.
Christians are to consider their neighbor more than themselves in their dealings in business, in the home and in politics. Imagine a world where people obeyed God in this way. Governments would no longer be corrupt. Families would no longer be broken by divorce. Business would be equitable to all peoples regardless of income or color or intelligence.
The world needs to be reconciled to God Who then reconciles humanity to one another. This message of reconciliation has been entrusted to Christians who are His ambassadors, as though God were making His appeal through them.
If the world would be a better place for everyone then every Christian must become occupied with their mission to win people to Jesus and to teach them to obey His commands.
