Overcomer,through a glass darkly.

I have just been reading the card board testimonies again, what jumped out was 'OVERCOMER', feel a bit doubtful about that today.....what have i overcome? everything i have overcome has been the Lord,He has done it,i should be happy with that....and i am, very happy that i am not that lost child in the wilderness anymore,i suppose it comes down to that old argument,where believers believe that God ordains everything,everything is done according to Gods will,we have no free will...Or He knows what we will chose...its hard to know what to believe,i suppose its just one of those mystery's we will only know the answers to when we meet the Lord.'through a glass darkly' at the moment!!!...Pre tribulation,Post tribulation, is another of those debates that each side believes they have bible verses to justify...puzzling!...
