sinking

So, i find my life a lot like im sinking... you know whats funny? it reminds me of the story of the apostle (possibly peter) who was able to walk on water only when focusing on Jesus, but when he would take his eyes off him, he would sink. When i focus on trusting God and beliving in his plan, i succeed, im not upset, i know i will make it with His help. When i focus on my own shortcomings and what i am unable to do with only my power, i realize how impossible it is for me to get through this program. I need to remember to focus on Jesus and not myself so i do not sink. I have an exam on Monday. please pray for me!! its a big one! (hense me not being able to post lately, ive been running around like a chicken with its head cut off)
