The opinion of those friends is that I should study doctrine and work at the church for 5 years before attempting preaching or evangelizing.
The SBC pastor said someone who just became a Christian yesterday can evangelize today because God will provide him with what to say.
Start slow,I agree with Trent praising and being sensitive to the Holy Ghost.
When I say start slow I mean to let the inward witness guide you to those in need.
It is a you know that you know what to do,many ignore that small voice.
We are of royal blood called to be servants.
You may find special people you are drawn to,at first a kind word a helping hand will open the door,be patient,but persistent they will see Christ in you through your example and love.
Salvation is something they will be drawn to as well,and you are the vessel God uses to guide and teach.
You know there is a void in there life and they do to.
So many have been turned off by church or their idea of church people.
Scare tactics may work for a moment,but relationships are for life.
As you continiued serving and studying the Word will start to flow,at this point you are growing.
Ask God for wisdom and discernment,you will be noticed by darkness.
Prepare to be interrupted when your getting close to winning a soul prepare for a battle.
We have Had people in tears ready to kneel down and someone barge in or cell phone wont stop ringing.Satan will fight but Christ will win.
You can be setting at home at midnight,and you know I have to go up to store or get gas.
One night this happened to me,when I got to the gas station there stood a woman pumping gas,my inner witness urged me to get her 20 dollars.
She was stunned,first she started to say how but started crying and thanking the Lord.
As I was walking away she was saying he answered and continued praising.
If I would have said no use to go this time,I would have missed this blessing.
Don't let anything stop you or the devil say its your pride,deep down you know your calling
The call of a Evangelist is a incredible gift.
As far as how long is relevant to how soon your faith will allow God to mold his clay.
Stay in the Word every day.
And soon you will be preaching to the lost
Gods blessing on all you do.
