'Thou art worthy, O Lord, to receive glory and honour and power: for thou hast created all things, and for thy pleasure they are and were created.'
It's easy to give God praise when everything is alright, but hard to even think of worship when things are not exactly going the way we want them to go. (I know 'cos I've been there). I believe that our strength lies in praising God which brings us joy in the Holy Ghost for the joy of the Lord is our strength. Nehemiah 8 verse 10.
Give thanks to God always whether good or bad, just try and remove sad thoughts from your minds, find something good to think about, maybe the fact that you are alive...sing a song, do a dance, shout hallelujah! Never allow yourself to be sad, 'cos that's where the devil wants you to be. Sadness breathes fear, it causes depression and everything negative. No matter what situation you find yourself in, always remember all things are working together for your good. Romans 8 verse 28.
