Nothing to fear to carry on the work of the Lord

I Corinthians 16:1-12
Paul asked Corinthians church each one should set aside a sum of money in keeping with his income on the first day of every week, so that when he comes no collections will have to be made.  Paul will give letters of introduction to the men they approve and send them with their gift to Jerusalem.
Paul gave directions for collecting money for the poor at Jerusalem.
If the Lord permits Paul hope he may go to Corinthians church stay with them some time. Paul don't want to see them now and make only a passing visit.
If Timothy comes, see to it that he has nothing to fear while he is with you, for he is carrying on the work of the Lord, just as I am.
Brother Apollos: Paul strongly urged him to go to Corinth with the brothers, he was quite unwilling to go, but he will go when he has the opportunity.
Why?
Apollos probably reluctant to return because of the split.
For donation should do it regularly as life of Christian in church to help the poor people.
Paul and Timothy carrying on the work of the Lord with nothing to fear, they are the example as his letter wrote. Let people learn from what they have done not only what they have said.
How?
Nothing to fear to carry on the work of the Lord, let other can see what I am doing. Do a good witness in my life.
