Ghoti,
I'll be praying for you, brother. I felt compelled to reply to you because for someone like me who never knew Christ for most of their life, the grass is definately not greener on the outside....there's just too many weeds to plough through.
A couple of years ago I felt like giving up being a Christian for some of the reasons you'd mentioned - no support or friends at church, plus I didn't read my Bible very often. Back then the only thing I was sure about was that God existed and yet I perceived Him as someone distant and not someone I could talk to. Because I was and am still a babe in Christ I didn't feel I could aspire to be like some of those church members around me. In my eyes they were soooo 'perfect' and here was I like 'filthy rags'. Little did I know back then that I was being deceived (Eph 6:12).
This is where I felt the need to write to you. I'll admit that at my lowest point I gave up - I had previously been an athiest and thought that life would be better if I left my faith behind, you know, less hassle and such like. I was under the illusion that I had no worries when I didn't believe. In reality, I was more unhappy than I had been when I believed - I just didn't know the solution (i.e Christ) to make my life happier.
So please don't lose hope, of all the friends you should lean on, lean on Jesus. I know it may sound a little crazy but what I did was, during my quiet time, I wept, I yelled, I asked...... I just talked to God. I told Him how I felt. And because our Lord IS real, He'll answer you. After much soul searching the Lord called me back to Him through the Bible (Jer 29:11-13 with emphasis in my case on verse 13).
Take each day at a time, but just speak with the Lord and as someone wrote earlier, take heed from the Psalmists "Be still and know that I am God..." (Ps 46:10) Listen to Him and wait, please wait for Him to come to your rescue.
Remember, because you're working for the Lord, you're 'public enemy number one' to the enemy. And he'll come at you with all his got to try to make you stumble especially with the 'grass is greener as a non believer' line.
Be blessed, and be rest assured that there will be many here who will offer up prayers of support for you.
God bless you!
