Well the most important things that you need to hold onto is reading your Bible daily and praying to God. Most people don't realize how much God wants us to be honest with Him. Tell Him how you feel, He's not going to strike you down .. He's going to correct you, thats what He's there for. I found out this year that when ever I pray to God i just need to be honest with Him. It's ok to tell Him .. " Look God i didn't agree with that or etc." There's no harm in talking to your FATHER in Heaven personally. Thats why He is our Father so that we can communicate with Him freely and honestly .
So don't shy away from prayer...even if you feel like you're just rambling on , just stop for a second and just laugh at yourself .. because ultimately that is a sign of wanting to pray a perfect prayer, and the only perfect prayer God loves is an honest one. Just tell Him " God I have no idea what i'm talking about, could you help me?"
Honest prayers will make God move in your life and He will change you and make you stronger, and I have witnessed that this year. It was an awesome feeling too. And i loved just speaking my mind to God about how I felt about our relationship ( which is what Jesus did and we need to follow Jesus' example)
You also need to pay attention to your Word. I was also at a point where i only prayed most of the time, but didn't read my Bible. That affected me and ultimately i have some downfalls and set backs. But i finally i got back on track and I am reading my Bible.. not often as i should.. but keep me lifted up on that.
So definately you should stay with the Word - God's daily bread. And prayer. Don't feel defeated. Let satan know who is in charge over your life and that he is under your feet. You do have the power to have all principalities of evil and darkness under your feet. You do have control over them and you can tell them to leave you alone in the name of Jesus, and they have no choice but to obey , because you proclaimed it in Jesus' name.
Stay strong and proclaim that you are a righteous man in Christ who loves God with all his heart and make sure you put on the armor of God everyday.
