There is no such thing as a “lost cause” for the Christian. The perfecting work that was begun at salvation will continue until we graduate into glory. Jesus has not and will not stop the work he started in molding you into His image. We must remember that Christ never leaves work unfinished.
The opposite of hopeful is despair or hopelessness. God does not want us to live hopeless lives. He wants to be the source of our hope. However to many times He is our last hope instead of our only hope. Hope in God is a confident expectation that He will keep His promises. If we are willing to make God our hope, joy and peace are sure to follow.
The Lord pays special attention to those in need. Jesus is not like the tyrants of the world that see the needy as a burden. Rather, he thinks upon them or you could say His heart is attentive to their needs. Rest assured, if you are in need God knows and cares.
We have all heard someone curse God when over some event in life. David, however, committed himself to blessing the Lord no matter what was going on. To bless the Lord is to praise Him. To know God is to know that he is worthy of praise at all times. Cursing God is out of ignorance of Him, blessing Him is out of knowing Him.
