Paul gives us the key to walking this out: "I live in this earthly body by trusting in the Son of God." This is how we get through Monday mornings, difficult Tuesday afternoons, and every challenge life throws our way—by trusting in Jesus.
We still have earthly bodies. We still get tired, frustrated, and face real struggles in a broken world. But the source of our life has changed. We live by trust in the One who loves us perfectly.
His grace is enough. His identity becomes our identity. His love is the final word on our worth—not what others think of us, not our financial situation, not our relationship status. His agape love far outweighs anything this world can offer.
