christians may have lost the purpose of why God came and died for their Sins. Which is-

19 Go ye therefore and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost,
20 teaching them to observe all things whatsoever I have commanded you. And lo, I am with you always, even unto the end of the world.” Amen.

But i am convinced that they are still those that have this 'command' written all over their heart. They are filled an heavy burden and heavy heart when they see a sinful soul and scorfers and judiciously with a burning unwavering desire and fervour follow up this soul to bring him/her into Gods marvellous light.

Tell ur story to how u journeyed in Ur Quest to winning a particular soul for christ,what U went through,how U inconvenienced and went the extra mile to ensure that someone repents from his sins. What strange and unusual method did you apply.

Your experience,or that of others will go a long way to encourage other christians to know if they have been living to win a soul for christ. Also those that are currently following up a particular lost soul will be strengthened if he/she is getting tired and want to give up on a soul,their spirit will be energized and encouraged in faith to continue.

Remember there is rejoicing and partying in heaven when a soul repents.

Some may want to say announcing your good deeds are wrong,but remember that paul in Acts and timothy made known many of his works of salvation so that We can know what it takes.

A brother when he was in the university faced a particular scenario when he was having his hair cut one night and there was power failure and no other means to continue his hair cut which have already gone half way. He already had it in mind to go for evangelism the next morning.

This didnt discourage him he went with his hair poorly cut and some sides Uncut and evangelised,but he testified that,that day was the day he had the highest turn up for people that want to give their life to christ.

Its obvious they is no act of believers of our time,but we only read acts but dont want our own acts.
