When I just believed and joined the local church community in Ukrainian town, I had formed an impression of a minister of God as somebody almost unreal like an angel. I thought they live differently, speak walk and talk all in a different way from Ordinary People. Then God led me to serve in Sunday school. In two years I became a leader and the challenging journey began.
For all these 12 years of being a Sunday school leader, God is leading me and teaching me what it means to be his servant. The main lesson I have learned through all of these years is to trust the Lord and follow His example. People can behave by their own understandings and motives, but we have an example!
Jesus taught his disciples how to serve people and each other in several ways:
1) By his own example
This was an object lesson about how to serve and be humble. Jesus used this situation to teach and to show them his attitude and then explained why he did it.
In actual fact, when you are full of desire to serve God, He puts you in a position when you have to learn how to be humble. And serving people is the best way to achieve it because they hardly ever appreciate what you do.
And it is totally fine, as you are doing it before the Lord first of all.
2) The attitude of the heart
He was doing only what he saw his father doing. In other words, he did what the heavenly father wanted. Jesus came to fulfill the will of God. He could have come in all the heavenly glory and everybody would bow down before Him. Instead, He came to die for many. His followers, the best what we can do is to live for Him as He died for us.
