Great Leaders not only overcome the limitations of the place and culture, but also time. Jesus set an example as a Leader who not only transformed the lives of people who lived at his time on earth, but even today people from different parts of the world are inspired by this one and the only Leader - Jesus Christ.
Jesus Christ said that a Leader should have a attitude like that of a Servant -
John 13:13-15 (NIV)
13 “You call me ‘Teacher’ and ‘Lord,’ and rightly so, for that is what I am. 14 Now that I, your Lord and Teacher, have washed your feet, you also should wash one another’s feet. 15 I have set you an example that you should do as I have done for you.
Jesus warned about the Leaders/Teachers of this world -
Matthew 20:25-28 (NASB)
25 But Jesus called them to Himself and said, “You know that the rulers of the Gentiles lord it over them, and their great men exercise authority over them. 26 It is not this way among you, but whoever wishes to become great among you shall be your servant, 27 and whoever wishes to be first among you shall be your slave; 28 just as the Son of Man did not come to be served, but to serve, and to give His [a]life a ransom for many.”
Matthew 15:14 NIV
Leave them; they are blind guides. If the blind lead the blind, both will fall into a pit."
The Self proclaimed Leaders are those who are blind (Spiritually) they don't know who the true God is. So they tend to show the others (followers) way, but ultimately they themselves will fall into the pit. It is very important to know what kind of Leaders we follow.
Jesus - Who is a Leader guides his followers into the path of righteous, truth and freedom. Because he is the "Light" of the world, the one who is the Path, "The Way, Truth and the Life". Rest assured for those who follow him, for those who come to him,
Matthew 11:28-29 (KJV)
28 Come unto me, all ye that labour and are heavy laden, and I will give you rest. 29 Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls.
We look at the world and see how generous God is, who gave us everything. Life, Hope, Health, etc. even before we could ask of him anything, he has given everything, in fact he said, "It is finished" - "Its done", any other Leader would ask first of what we have done for him or for ourselves, or at least what we are going to do. That's very important for life, as to what we have done, what we are going to do, but when it comes to Salvation, Forgiveness, all the things that we can do or done will never compromise God's quality of Life. So, God took the initiative, he not only forgives the Sin, but also gives the direction for the sinner to find a way to live a Godly life, he often gave directions to the people who considered to be sinner, low in society, we could see how he valued such people like the "Women caught in adultery", "Women at the Well", "The blind from birth", "The Leapers" etc.
