Christians need to set an example before others. Once a person comes to the leadership role it is more important. A person has to be very careful about how he behave.
Paul says few things to Timothy Like this:-
1 Tim 4:12-16
Don’t let anyone look down on you because you are young, but set an example for the believers in speech, in life, in love, in faith and in purity. Until I come, devote yourself to the public reading of Scripture, to preaching and to teaching. Do not neglect your gift, which was given you through a prophetic message when the body of elders laid their hands on you. Be diligent in these matters; give yourself wholly to them, so that everyone may see your progress. Watch your life and doctrine closely. Persevere in them, because if you do, you will save both yourself and your hearers.
Paul then says to Titus that:-
Similarly, encourage the young men to be self-controlled. In everything set them an example by doing what is good. In your teaching show integrity, seriousness and soundness of speech that cannot be condemned, so that those who oppose you may be ashamed because they have nothing bad to say about us.
Setiing an example before others should be a concern to us. Remember that you influence a lot of people and many look up to you even though you may not know it. Hence its very important that we set an example for others to follow.
May God Bless You!
