Whatever begins as an unexpected call or starts in a small way tends to have potentials for becoming great especially when handled with seriousness of purpose. What has an end must surely have had a beginning, great or small. If at first there is a feeling of inadequacy, it is not unusual to first appear like that, but a Christian should know or is expected to have learnt the biblical history of characters like Noah, Abraham, Moses, Joshua, Jeremiah, Peter, and even Saul, who after conversion became Paul the Apostle. Moses and Jeremiah openly tried to adduce reason why they were not qualified to be a Prophet of God.
When the sin of the then world was too much for God to condone, He called on Noah to build an ark in which those qualified to be spared were to be kept when there was to be a deluge to wipe out the exceedingly sinful people. He obeyed by following the dictate of God concerning the measurement as well as the type of wood to use. No one has ever built an ark like that; so Noah was only daintily following instructions from God without any template to adopt.The people confronted him with discouraging attitude but he remained undaunted. At the end, he was saved along with the specified people, plants and animals as well as birds, while others perished in the deluge.
Abraham did start life as Abram before God asked him to leave his fatherland and go to a place he would show him. It was more or less a wild goose chase. God knew before hand what stuff Abram was made of. He obeyed and set out with his father Terar, Sarai his wife, and his nephew Lot. Based on his character and love of God along the line, his name was changed to Abraham – Father of many nations. Tripartite covenant began from him and God fulfilled it all. God prospered him immensely.
Moses was born in Egypt many centuries after the death of Joseph, a Jewish Prime Minister of Egypt. It was at a time when the patriarchal blessing per the covenant was at its lowest manifestation because the Jews seemed to have forgotten their God and had embraced the god of their host in Egypt. Although, they were suffering an exploitative slavery, they were just producing healthy children unlike the Egyptians. This fear-driven envy made Pharaoh to order the killing of all male children born by the Hebrews. God orchestrated saving the life of Moses and even got him to be very well preserved in the palace with Pharaoh watching him grow as Prince of Egypt. His first forty years was in the palace, the next forty years he was a fugitive in the land of Midian. At the end of the second segment he had God’s call to be a deliverer of the Hebrews. He found excuses to avoid being killed for homicide committed in Egypt and basically he was a stammerer. God provided Aaron and Miriam to assist him. He accepted the challenge with humility and was able to demonstrate the power of God over Pharaoh and the kingdom of Egypt through the ten plagues. This represented the third segment of his life. God granted him the enablement to lead the children of Israel out of Egypt, through the wilderness and to the Red Sea. He led the stiff-necked People of God across the Red Sea with so much trouble from the people he was leading. He could not resign and the people could not fire him because it was a divine assignment from God. There were times when he was on the verge of being stoned, at another time, he prayed God to kill him for the sin of idolatry committed while on Mt Sinai receiving the Ten Commandments- The Decalogue or God’s Constitution – meant to enable the children of Israel to live right before God. God showed him the land that was flowing with milk and honey but did not allow him to get there and he was 120 years old when he was no more.Exodus 2: 23-25 and 3: 1-22.(KJV).
Looking at the circumstances surrounding the birth of Samuel, there was no doubt that his call to serve God was surely irresistible. 1Samuel 3: 1-21 (KJV). At the time of Samuel’s full ministry, one has to recall that Prophet Eli had died as well as his two sons Hophni and Phinehas for their uncontrolled bad behavior in the house of worship. Prophet Samuel was instructed to go and anoint David as King designate since God had rejected Saul and had already been serving in King Saul’s army of Israel. The first spectacular victory was the encounter with the Philistines’ war-lord Goliath. David had so many challenges to face with Saul who tried to get rid of him out of jealousy and the obvious reason of David’s being a preferable successor to King Saul in preference to Prince Jonathan, whose friendship with David was greater than that of twin brothers. David had a humble beginning but his penchant for loving and always depending on God as well as tending his father’s sheep even at the risk of his own life became the obvious human reason why God found him a better alternative to King Saul when he violated the divine rule on division of labor between the king and Prophet Samuel. The Omniscient God what destiny each individual carries and so HE did not have any problem choosing who to do His job whether easy, difficult, dangerous or peaceful.
David road to rulership was with much difficulties, trials and triumphs, but all said he was a perfect fit for the job. King David was declared very dear to God. He was a human being like me or you but was head and shoulder higher in the virtues of obedience, contrite heart ready to admit guilt without rationalizing over his sin even unto God. He, as a ruler in his era, was remarkable and really inimitable. He fought battles and won all just because he made God the winner of battles he fought as he was always making God the fighter of battle that he ever led. David was able to bring all the 12 tribes of Israel together with headquarters in Jerusalem, the city of David and God promised him that the throne of David shall never lack who to occupy it. He never defied or rejected God like Kings Jeroboam and Jehu of Northern kingdom based in Samaria and did not usurp the Saul’s kingship like Hazael did to King Ben Hadad of Syria. 2King 8: 1-15 (KJV) The reign of King David became a reference point in the history of rulership in Israel. So also Jeremiah received divine call, Jeremiah 1: 4-10 (KJV). He like Moses, tried to justify why God need not call him to do a task as onerous as being a Prophet over the Israelites. He claimed, “I cannot speak because I am a child”. God in a trance touched his lips signifying putting His words in Jeremiah’s mouth. He throughout his life did the work of God with passion, weeping as he has spiritually known the impending period in exile.
Paul was another example of those God called into his vineyard. He was efficient and very effective in taking orders from the Priests and Chief Priest to go and hound the emerging disciples of Jesus after Peter has assumed the leadership of the apostles. Lord Jesus had to virtually “arrest” Saul of Tarsus on his way to Damascus with the intension to bring any disciple bound to Jerusalem for punishment. Acts 9: 3-6 The passage reads thus;

“As he journeyed he came near Damascus, and suddenly a light shone around him from heaven. Then he fell to the ground, and heard a voice saying to him, ‘Saul, Saul why are you prosecuting Me?’ And he said, ‘who are you Lord?’ Then the Lord said, I am Jesus, whom you are prosecuting’. ‘It is hard for you to kick against the goads’. So he, trembling and astonished, said Lord, what do you want me to do?’ Then the Lord said to him, Arise and go into the city, and you will be told what you must do.” Mandate received, Paul used his hitherto energy for destroying the Apostles to encourage and even charted a new course of evangelizing the heathens or the worshippers of idol. Paul the apostle, did so much to take the gospel to the Gentiles more than any of the apostles in spite of his personal ill-health and risk to his life including shipwreck. In it, the prisoner became the ship’s Captain. He gave them the massage of hope that no life would be lost.
