Have you ever realized that one of the commands in the Bible is to rejoice? We seem to skip over passages like that and think, "Well ya know, it says rejoice." But do we truly rejoice on a regular basis?
Phillipians 4:4 says, "Rejoice in the Lord alway: and again I say, Rejoice." It says to rejoice always. But it does not simply say that. It says to rejoice in the Lord. I would submit to you that many Christians have trouble finding joy in their everyday lives, because they do not have God in their everyday lives. How can we "rejoice in the Lord," when we do not keep the Lord in our lives?
God wants us to rejoice, but in order to do that, we need to remember our reason for rejoicing. We need to be thankful for what God has done for us. Have you remembered what God has done for you? Do you remember how great God is, and how much He loves you. I would challenge you to put these things in your remembrance. Ask God to help you rejoice in Him. I know He will!
"Rejoice in the LORD, O ye righteous: for praise is comely for the upright." – Psalm 33:1
