I am not sure I am getting what you are saying when you link lack of faith and anticipating loss and lack.The reason the people fail to follow Jesus is they have a lack of faith. They don’t think He’s going to come through for them. They anticipate loss and lack if they trust Him.
Yes, Jesus is trustworthy, but it doesn’t mean that anticipating loss and lack is wrong. It is simply being realistic – and maybe, if we look at Christ’s life on this earth, it could even be seen as living as He lived.
For some of us, making the choice of the Church is indeed costly, in a very down-to-earth, monetary way, and the loss and the lack could become very real.
The day I enter full communion, I will, among others, lose my job, go into debt, and possibly become homeless, because divorce is very much a possibility if I do this.
All this in order to leave a Protestant church in which I am honest enough to recognize that the Holy Spirit is at work, too, in spite of all its faults and its incompleteness.
I hope I’m not coming across as bitter, because I’m not. But accepting that there will be a price (that, as I would say in French, I cannot have all at once the butter, the butter’s money, and the dairymaid’s smile) has been a recurring issue for me in spiritual direction ; and it’s not just about accepting that the hard things will not go away, it’s about accepting that they will possibly get much worse. Accepting loss and lack, for Christ’s sake. Accepting, in my case, that I could very well be choosing lifelong loneliness and material poverty. Things I don’t have it in me to face with courage and love, but, just barely, with clenched teeth and despair, as my own way to the Cross.
Maybe I’m just particularly tired and grumpy tonight, and getting too easily rubbed the wrong way. Please accept my apologies if I said something offensive, or if I misread you.
