When the Lord started His mission He declared clearly to His parents ‘I must be about My Father’s business?’, Luke 2:49, which meant that my heavenly Father’s strategy is to correct the way of life and future of the world including My forefathers descendants. He also said to the Jews more than once ‘You heard it was said ….but I say to you….’, Matt 5:38, and ‘Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil’, Matt 5:17.Furthermore, to prove Himself to them, He performed numerous miracles, including creating eyes to the blind, healing the sick, raising the dead and also showing His power over nature. However, they did not accept Him but rather rejected Him and crucified Him. So, with His eyes which searched the thoughts of the hearts of the Phareses and with His divine foreknowledge, He had appointed twelve disciples who were children of the Israel and taught them everything they could perceive about Him and the kingdom of God. In preparation for His ascension, He promised to send them His own Spirit to remain always with them and to take from what is His and deliver to them, John 16:14. Indeed, ten days after His ascension the Holy Spirit descended upon the disciples and filled them with God’s power and wisdom, by which they preached the good news of the salvation of the world to all people starting from Jerusalem to the three continents. They made disciples, and established churches calling all nations to return to the Lord and accept His salvation in order to be united to Him and have eternal life.
