Confidence
Self doubt will attack your self worth, self esteem and your confidence. Without confidence nothing much will work, or if it does it will only work for a short while. It takes confidence to successfully make anything turn out right. God's Word says in Hebrews 10:35 " Cast not your confidence away".
Satan works extra specially hard to take your confidence away from you. Hang on to it and be confident in everything you do. If he can take away your confidence he can make you doubt what the Word of God says is true. He also, wants you to doubt yourself by telling you that whatever you do, it will not be successful or you will fall flat on your face. This causes all manner of thoughts to flood into your mind and that is Satan's number one plan, doubting yourself. With this doubt inside you, your confidence takes flight. Anytime there is doubt, go to The Word and see what God has to say about what you're feeling. Everything you will ever want to know lies in between the covers of The Holy Bible. It will keep your confidence in tact if you'll just follow it's lead.
Confidence must play a big part in all you do, your thoughts, prayers, your tithes and your work. Like when you pray be confident in Christ Jesus that no matter what I ask it will come to me as in 1 John 5:14-15. Just always remember that confidence comes not from what you have done for God but confidence comes from what God has done for you.
