"And an highway shall be there, and a way, and it shall be called The way of holiness; the unclean shall not pass over it; but it shall be for those: the wayfaring men, though fools, shall not err therein. Isaiah 35:8"
The almighty God wants us to think like Him. He is a Holy God and calls His way a highway: this is the sure way of prosperity, health, and sound mind that God wants for us.
Holiness is equated to the highway of God: it has to do with abstaining from anything which is ungodly.
The sure way to live a holy life is to do the things that Jesus Christ did whilst on earth; He was the express image of His very person.
It pays to live a holy life; it is the sure way to see/experience God, Matthew 5:8. Don't be a fool because fools will always err and miss the kingdom of heaven.
Be wise to enjoy God and our Lord Jesus Christ. Praise the Lord!
