What if that one situation in your life never changes? What if God told you today that it's going to be part of your life until you leave this earth? How would you react? And then, after thinking about it, how would you respond?
If that situation is a huge weight on you those questions are overwhelming, but they're important.
First, because all we have is today. Living in the moment is how to live with an eternal mindset. It is how we can be content in all circumstances. You might just have today. Do you want to spend the rest of your life in stress and worry and fear?
Second, we must learn to be content even if we are facing the worst thing we can think of.
Paul writes in Philippians 4:11 that "I have learned to be content in whatever circumstances I am."
That doesn't mean you have to like the circumstance. But you can be content even in an awful situation because you know Father God is in charge and taking care of you and will get you through. If you learn contentment in this way nothing this life throws at you will be able to shake that inner peace God offers to us.
A few verses before the one I already quoted, Paul writes, "Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all comprehension, shall guard your hearts and your minds in Christ Jesus."
I don't know what the future holds for any of us. A future on this earth can be cut short quickly. A future on this earth can take a downward turn rapidly. We all will face death of someone we love (unless we are that someone who dies). We all will face disappointment. We all will face crushing weights of impossible problems. What a testimony to this world it is when we can face all of this while living in Christ!
Very likely one of the two main-party candidates in our current presidental election will win the November election. No matter who wins I believe our country is in for major changes.
2 Timothy 3:12 says, "And indeed, all who desire to lively godly in Christ Jesus will be persecuted."
We must learn to be content in all situations. We must become rooted in the Word of God to withstand the worst this world can throw our way. The thing about spiritual warfare (and that is what persecution is) is that it always feels very personal. We often don't recognize it at first because it feels like an attack on us personally -- nothing to do with our faith. if we have done nothing wrong and there is nothing we need to rectify, very likely it is spiritual warfare. We haven't faced real persecution in this country. But it is coming.
That is a bit of a tangent but it all relates. Learn to be content in all situations and Jesus will shine out of you so brightly people won't be able to ignore Him."
Stephen, the first one killed for Christ, was shining like this before his death. Acts 6:15 says, "And fixing their gaze on Him (Stephen), all who were sitting in the Council saw his face like the face of an angel."
