The nature of missions in itself is the proclamation of the biblical and historical Christ as Savior and Lord in order to persuade men so that through Him receive forgiveness of sins and reconcile with God. The Church is at the core of the divine purpose and it is the instrument for spreading the purpose. The evangelism and world mission require the church to take the whole world the whole gospel in mutual work cooperation. All churches should ask God and themselves what they should be doing to reach the world, revealing the universal character of Christ's Church. The missionary urgency - With more than two thirds of humanity has not effectively evangelized, as a church, we feel ashamed of our negligence. Each generation being responsible for his generation this is the time of fervently pray church aiming at total world evangelization. The culture of a people is partly good and elsewhere is bad due to the Fall, so it should always be tested and judged by Scripture, so it can be redeemed and transformed for the glory of God. Therefore the world mission requires the development of strategies and new and creative methodologies. The freedom to practice and propagate Christianity according to the will of God is our right. Missions will only be achieved with a church full of the Holy Spirit, and He who convinces the man of sin. The Holy Spirit is the spirit of missions and has a deep interest in the nations. The second coming of Christ represents a motivation of the missions. We believe that the interim period between his ascension and the second return must be used for the fulfillment of our mission as God's people. Missionary work can not stop until Jesus Christ did not come. Can you imagine one day see the most distant and hard people are reached by the gospel? I hope so, for this is God's will that all be achieved. So the revelation of Rev. 5.9 is wide and clear when he says: "They sang a new song, saying, Thou art worthy to take the scroll and to open its seals; . because you were slain, and with your blood you purchased men for God from every tribe and language and people and nation "Come over to Macedonia and help us, it comes to you with this proposal: Wake your heart to the great need of World: The Gospel.
