I'll define endurance as an ability for someone to preserver during a difficult situation without being weary until the victory is achieved.
The dictionary definition is the ability to hold on during an unpleasant or difficult process or situation without giving way. Both definitions are correct. Take an example of this: you found out that you are obese your BMI is beyond the normal range, and the doctor instructs you to begin daily exercise and dieting to reduce your weight, so that you may avoid major trouble in future like diabetics and heart problems. You faithfully began the journey. How did it feel at first eating food you didn’t like, jogging and doing tough exercises? It’s tough and hard, but you endured because you knew the outcome will be great.

For me that the definition of endurance. Where you hold on the pain and tough season until the breakthrough has come. We know from the scripture Psalm 30.5 that weeping may last through the night but joy comes with the morning. The breakthrough will eventually come that’s for sure. Therefore, Christians are called to endure in every season of life, no matter how tough things are. Apostle James tells us in verse 2 of the first chapter of his book to count it all joy when we go through hardship, not because it’s a good moment but it has a reward and your faith is made stronger through it. He went on and tell us in verse 3 that when faith is tested endurance has a chance to grow. Our faith is daily tried as believers, but if we endure it grows, we can handle even tough periods that will come in future, like the great persecution.

You may ask how then should we endure? Through faith, joy and patient. Joy is a fruit of the spirit. You can’t fake joy it flows from your heart, its divine and doesn’t depend on the situations around you. Joy is built-in faith when you know who you are and the victory of God you will endure, and hold on during difficult times.

In verse 6 of James 1, the apostle says that when endurance is fully developed you will be perfect and complete needing nothing. Wow, that amazing when you allow you faith to be tested, endurance grows and when it has fully developed you are made perfect and complete.

Lastly, we are encouraged to endure because of what verse 12 says that God blesses those who patiently endure, take note of the word patiently, testing and temptation. Afterwards, they will receive the crown of life that God has promised to those who love Him.
Therefore, brethren in the midst of what you are going through as a person, we as a nation and globally, the Lord is asking us to endure and hold on unto our faith. He is for us and never against us, the breakthrough will eventually come. Let your faith be strong in the Lord. He is our source of joy and strength.
