Struggling

Right now I don't really know where I stand. I'm struggling with so many things, that I feel that I may be at my break point and just might give up on even trying anymore. For some reason the more I try to draw closer to God the more temptations and tests come my way and I truthfully don't feel like I'm strong enough !!! I'm constantly reminded on a daily basis of what I've done, how far away I am from Him and what I am not !!! The Bible says through our flaws He makes Himself perfect and that He who has begun a good wrk in you will complete it til the day of Jesus Christ, but for some reason I can't seem to convince myself that that will ever happen...I know that the only reason why I am thinking that way is because I've allowed satan to mess with my mind but he is so slick and manipulative and he presents these plausible reasons as to why I should just give up. I just don't know what to do please keep me in prayer !!!
