The believer is forever secure in the keeping power of the Lord Jesus Christ. Therefore, he walks rejoicing in the Lord: he rejoices no matter what confronts him.
This is how the Apostle Paul felt as he sat in prison and wrote these words: ‘Rejoice in the Lord always. Again I will say, rejoice!’ ~ Philippians 4:4. Paul was full of joy because he knew that no matter what happened to him, Jesus Christ was with him. You see, ultimate joy comes from Christ living inside us!
When a person rejoices in the Lord, his mind is focused upon the Lord, upon what the Lord has done for him. And the mind cannot be in two places at once. If it is upon the Lord and His glorious salvation, then it cannot be upon the trials and false teachings of this world. No matter what confronts the believer, no matter how terrible the trial, we know that we are in the care of the Lord Jesus Christ! We know that there is nothing that will separate us from The Lord or His love.
Therefore, we can say with the Apostle Paul ‘I Always Rejoice in the Lord’!
