The Word of God holds God's power and it brings joy, comfort, love and lots more to those who receive it and proclaim it.
Whenever we receive God's word we get hold of His power and then we become a threat to Satan. Now that we're a threat to Satan, he wants to steal God's word from our hearts by throwing at us problems, worries, fears.
People tend to ask God "why is that until we have received your word only then do problems come?" There are only two things that can happen... Leave God or grow stronger in Him.
What people usually don't see is that whenever we have God's word we are a threat to Satan. They don't know that Satan wants to steal God's word by deceiving us using bad circumstances.
At Job 5:22 is says "At destruction and famine thou shalt laugh."
We should rejoice whatever happens, trusting God that He will deliver us. "Amidst affliction yet will I rejoice" was written in Habakkuk 3:18
1 Thessalonians 5:16 says "Be joyful always." Let us always rejoice in God for He has overcome, He is victorious.
Satan wants to deceive us, but he doesn't know that his day is coming. "The Lord laughs at him; for the day is coming." - Psalms 37:13
Do not fear Satan, and don't let him steal your joy. Remember he doesn't know how to handle a joyful believer. It drives him crazy.
We win by not allowing Satan to get our joy whatever bad things he throws at us. When you are at your lowest point, where you feel like you can't do it anymore. Don't give up, Satan has already thrown his best shot at you. If you choose to stand and rejoice in God, you won.
"Rejoice, again I say rejoice!" - Philippians 4:4
"The joy of the Lord is my strength" - Nehemiah 8:10
