In bygone days folk in the UK had at least some basic knowledge of Christianity. Now at least '1 in 500' couldn't say what a Christian is according to the Bible. We have the Mormon 'jesus'; JW 'jesus'; RC 'jesus'; Liberal 'jesus'; LGBT 'jesus'; charismatic 'jesus'; new evangelical 'jesus' etc.
According to an Open Air Ministry they have no knowledge of any saved in the last few years despite the vast distribution of tracts. Individually we know tracting a whole village, it would be realistic to hear then any who professed Christ.
Many tracts are pretty shallow and some dare I say useless. I'd wait a long time for a tract that explained 'sin' and 'repentance' and why we need Christ in the first place.
There is the above booklet and also 'THE TERRORS OF HELL' WILLIAM C NICHOLS. If we hope folk will pick up a weighty Bible and read, then why do we think they wouldn't first benefit from tracts in a booklet form with a far better explanation of personal sin and the Divine remedy.
Have a look at the above booklet available free or for 'pence' and compare it with some modern day tracts? Evangelism needs to be first 'biblical'...
