The attack can come from anywhere
It does not matter how 'strong' you are in the Lord Jesus; satan is cunning and will setup situations to get you off track, to fall, to silence Godly work... This happened to me and to tell you the truth it wreaked havoc in me! Yes I know the scriptures. But it still wreaked havoc. Satan was coming from every direction.
It started out with a younger Pastor telling me that me and my generation has screwed up, referring to programs in the Church. Then the attack got more person. Started a bible study and a member of that study reached out to other men. Well the Leaders of the Church told those men it was an unauthorized bible study and more. Soon men we not talking to me... Some even would not even greet me... others who I was close with would 'tolerate' me. Then comes another blow by a Pastor, you would never be a leader, these young men will be better than you. Sometimes it is a good thing that you follow Jesus Christ; that you have worked on the anger issue.
What do you do? Well, first you need to put anger aside, for anger of man will not accomplish the rightness of God. James 1:20 Then you need to check yourself. Now that can be hard. Well with the bible study it was not malicious and the intent was not of pride. The putting on the armor is important! Also it is important to check yourself! Sometimes Satan will use you as the point of attack; that is when you are not doing what is right in God's eyes(His will). Now with that what do you do? Needed to go to the book of Eph. chapters 1 and 2. to remind myself who I am in Christ. It doesn't matter how knowledgeable you are of these scriptures you need to pickup the bible and read them, soak them in and pray them. Use the word of God that corresponds to each part of the armor of God. The armors power is in the words of God.
Now one must forgive the person(s) that where part of the attack. Yes this is of utmost importance! This might be the hardest thing to do; but it is of great importance in order to move forward(standing) against the real enemy, Satan. If you miss this step the enemy will see that "weakness" and exploit it. You see the armor is help you to stand firm; to resist! The goal is that Satin will flee; or stop attacking presently. And most important is for God to strengthen you and your faith being built up.
