"My brethren, count it all joy when ye fall into divers temptations; knowing this, that the trying of your faith worketh patience. But let patience have her perfect work, that ye may be perfect and entire, wanting nothing." James 1:2-4.
"Let patience have her perfect work...." test and trials don't perfect us. It is what we do with them that is important.
We are not perfect because of a bunch of problems come our way. We are perfected because we stick with the Word of God in the midst of those problems and patiently endure. That's when patience has its perfect work.
Patience is constant endurance. When we walk in patience, we stay consistent throughout our problems. We base everything on God's Word.
We can't get up in the morning and check to see how we feel about what is going on in our lives or bodies. We must open our Bibles and tell ourselves how we feel according to the Word of God.
