Is our rejoicing short lived ? I noticed mine was. So I asked the Lord why ? I noticed my rejoicing were based on my perception that things must be favorable to me. Apostle Paul who wrote " Rejoice always" experienced unfavorable circumstances like ship wrecked, stoning, beatings etc. so where did he based his rejoicing ?
I believe he based his rejoicing on the finished work of Jesus Christ on the cross. The cross shows that Jesus fulfilled His mission to save us and will fulfill His other promises to us.
Does God take away our worries ? God told us not to worry, so if we worry that is what we choose to do. Trusting God does not mean for us to do nothing but to do the will of God. What then is the will of God ? We can know the will of God by fervent and continuous prayer or praying without ceasing.
Let us always seek the Lord or the kingdom of God and His righteousness.
