My tip is that you need to know God and His will and have Him work.
What is this evangelising that appears to be an activity carried on without God, and without His direction?
Why don't you rather listen to Christ ... without me ye can do nothing.
Of course nobody believes that because they all think they must go about evangelising, whatever that is.
Are we not supposed to cease from our own works? So that God may work?
Has it not occurred to you that we ought to be seeking for God to work? Or do you not really believe that? Do you think He cannot work without your or our help?
That is more the mark of it isn't it?
It is far too humbling to realise that we can do nothing, nobody wants to believe that, though that is precisely what Christ tells us and is precisely the case.
It is far to demanding to seek God in prayer and to seek His will and His Kingdom to come through His power.
Yet that is what Scripture declares.
Have you never read : If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.
Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples.
Does He really mean that the fruit comes from abiding and asking and not from our running about 'witnessing' and 'evangelising'? Does He really mean He just may use some other means in response to our abiding and praying?
Is abiding and asking just too demanding, too searching?
If we are not abiding and praying how can we be fit to reach others anyway? Just maybe He has His own persons who He will choose for the harvest. Pray ye therefore the Lord of the harvest, that he will send forth labourers into his harvest.
That's my tip. Forget what men say and seek God and His will and hear His voice to you, abide in Him and do nothing without complete dependance upon Him and His working. After all, even Christ could do nothing but what he heard or was shown by the Father.
Are we any different?
