This call have been repeated by God several times
From the Old Testament we can find these examples
Abraham have been called in a similar manner as it is clear from the book of Genesis (12:1-4)
1 Now the LORD had said to Abram: "Get out of your country, From your family And from your father's house, To a land that I will show you.
2 I will make you a great nation; I will bless you And make your name great; And you shall be a blessing.
3 I will bless those who bless you, And I will curse him who curses you; And in you all the families of the earth shall be blessed".
4 So Abram departed as the LORD had spoken to him, and Lot went with him. And Abram [was] seventy-five years old when he departed from Haran.
Abram responded having faith that God gave promise. He was fascinated by the Person of God and was eager to be comforted through His gentleness which made Abraham feel real rejoice.
Abraham was obedient so that when God asked him to give his son Isaac as a burnt offering he did not argue but went on till God stopped him
All these made him deserve to be called the father of the faithful.
A sign from a great sight as in Genesis 3
3 Then Moses said, "I will now turn aside and see this great sight, why the bush does not burn".
Look carefully because Moses came near to examine well what he have seen from afar God started to speak to him and called him to be His prophet.
4 So when the LORD saw that he turned aside to look, God called to him from the midst of the bush and said, "Moses, Moses!" And he said, "Here I am".
Imagine how blessed can be he who is attentive to the voice of God and follows his call to do what is good for himself and the others.
You may apologise saying I am sorry I am not ready to serve. This what happened with Moses
11 But Moses said to God, "Who [am] I that I should go to Pharaoh, and that I should bring the children of Israel out of Egypt?".
Moses went on apologising Genesis 4
10 Then Moses said to the LORD, "O my Lord, I [am] not eloquent, neither before nor since You have spoken to Your servant; but I [am] slow of speech and slow of tongue".
We find here that The Lord assured him saying
11 So the LORD said to him, "Who has made man's mouth? Or who makes the mute, the deaf, the seeing, or the blind? [Have] not I, the LORD?.
12 "Now therefore, go, and I will be with your mouth and teach you what you shall say".
God is not doing things haphazardly he knows yourself better than you do, and He promised Moses
- To be with him.
- To teach him.
- Let him speak and had no need that anyone should testify of man, for He knew what was in man (Joh 2 : 25)
Giving up is the response in the third example:
God gave an order to Elijah to anoint Elisha as a prophet. Elijah found him and laid his dress on Elisha who immediately realized what he meant to do. Submitting himself to the order of God he started by giving up his wealth as burnt offering (1 Kings 19:21) So Elisha turned back from him, and took a yoke of oxen and slaughtered them and boiled their flesh, using the oxen's equipment, and gave it to the people, and they ate. Then he arose and followed Elijah, and became his servant.
Our Lord calling His disciples
He met them and asked them to follow Him. This occurred several times. Let us have a look to this as it is repeated in three Gospels Mt 4: 18-22, Mk 1:16-20 and Lk 5: 1-11
In Mt 4: 18, "And Jesus, walking by the Sea of Galilee, saw two brothers, Simon called Peter, and Andrew his brother, casting a net into the sea; for they were fishermen.19 Then He said to them, "Follow Me, and I will make you fishers of men. 20- They immediately left [their] nets and followed Him. 21 Going on from his brother, in the boat with Zebedee their father, mending their nets. He called them. 22 and immediately they left the boat and their father, and followed Him."
Here we find that Peter and Andrew left everything, so did John and his brother James. The Lord said to them that they will become fishers of men (to bring people to believe in him who is coming in the name of God)
In St Mark Gospel it is clear that they were owners of the boats and not only employers.
More details are in the gospel by St Luke chapter 5
4 When He had stopped speaking, He said to Simon, "Launch out into the deep and let down your nets for a catch".
5 But Simon answered and said to Him, "Master, we have toiled all night and caught nothing; nevertheless at Your word I will let down the net".
6 And when they had done this, they caught a great number of fish, and their net was breaking.
7 So they signaled to [their] partners in the other boat to come and help them. And they came and filled both the boats, so that they began to sink.
Simon obeyed the Lord and went to the deep waters while having faith in God
8 When Simon Peter saw [it,] he fell down at Jesus' knees, saying, "Depart from me, for I am a sinful man, O Lord!".
9 For he and all who were with him were astonished at the catch of fish which they had taken;.
Feeling unworthy to have God in his boat after the miracle Simon asked the Lord to leave him. But The Lord encouraged him as He usually does with any one who is feeling unworthy to be preaching His name.
10 and so also [were] James and John, the sons of Zebedee, who were partners with Simon. And Jesus said to Simon, "Do not be afraid. From now on you will catch men".
11 So when they had brought their boats to land, they forsook all and followed Him.
You can say that those disciples were also disciples to John the Baptist that is why it was so easy for them to follow Christ. But I can also tell you about Mathew the tax collector who was pleased by the call from The Lord and accepted him as his honorable guest . You can find this in Mt9:9-17, Mk2:13-22, Lk5:27-39
9 As Jesus passed on from there, He saw a man named Matthew sitting at the tax office. And He said to him, "Follow Me" So he arose and followed Him.
If you will hear His voice, Do not harden your heart but do just as both Mathew and Zacchaeus (Lk19:1-10)
5 And when Jesus came to the place, He looked up and saw him, and said to him, "Zacchaeus, make haste and come down, for today I must stay at your house".
8 Then Zacchaeus stood and said to the Lord, "Look, Lord, I give half of my goods to the poor; and if I have taken anything from anyone by false accusation, I restore fourfold".
Rejoice when you are asked to serve in any field in the church, it is a blessing for you. Let any wealth of this world be nothing versus being heir of the kingdom of Heavens which He promised to those who love Him.
