It seems there are very few people who are consistently content with life. It's more common to be up and down mentally and emotionally, depending on what our circumstances are. So I want to ask you: How content are you? Are you consistently enjoying your life?
God loves us and has a good plan for our lives. Jeremiah 29:11 says His thoughts and plans for us are "for welfare and peace and not for evil, to give you hope in your final outcome" (AMP). And John 10:10 says Jesus "came that they may have and enjoy life, and have it in abundance (to the full, till it overflows)" (AMP).
It was such a revelation for me when I realized that God wants me to enjoy my life now, and not just barely get by, hanging on until I get to Heaven. It was also a life-changing revelation when I understood that my joy and contentment don't have to be based on my circumstances. In Christ, I can learn "how to be content (satisfied to the point where I am not disturbed or disquieted) in whatever state I am" (Philippians 4:11 AMP).
