May our thoughts remain in the Lord.
As for true peace, we must recognize that it does not depend on the circumstances we live in, but on the person in whom we place our trust. Most of the time, fear and anxiety overwhelm us because we believe that we can control situations with our own strength.
But it is God who promises that if we keep our heart and mind focused on Him, fully trusting that He is always working in our favor, He will give us that peace that surpasses absolutely all understanding.
When we talk about persevering in God, it means that we must trust even when we see no way out; God is still in control of everything. Persevering also means learning to rest in His promises and His faithfulness, having the full certainty and security that He will never leave us. It is key to know that we will not have an absence of problems, only that God is with us even in the midst of problems.
You will keep in complete peace him whose mind is stayed on you; because he has trusted in you.
Isaiah 26:3
