Psalm 37:18: The Lord knoweth the days of the upright; and their inheritance shall be for ever.
The righteous are always led by God. He watches over them. His eyes are always set upon their welfare. They will all have their equal share of joy and sorrows, but still God ensures that everything will work out for the good of them. Their inheritance is forever in heaven. Nothing or nobody can cut short their expected stay on earth.
Many are the afflictions of the righteous, but the Lord delivers them out of them all. His love is always for those who walk uprightly. He knows exactly how long they will be on this earth, what kind of ordeals they are going to face, if they will succeed in them or not, how many more challenges they have to face, etc. He knows their going and coming. He knows their every breath and every detail. If they are surrounded by troubles or difficulties, He knows He has to be with them and protect them and guide them. Their inheritance will be in heaven forever and ever. The righteous are allowed to live their full lifespan here on earth. They will be victorious when struck with calamities. The wicked are not so. Their days will sometimes be cut short and they can even have bad to worse times.
Trust in the Lord with all your heart. Do what is good and pleasing to the Lord. Honour Him in all your ways so that He will always uphold you and guide you in all truth. Your every single day will be taken care of by Him. Continue to be the righteous you, washed by the blood of Jesus.
