Years. That can help, although it doesn't necessarily do so.
Experience. That also broadens perspective, although once again, it doesn't necessarily do so.
Age, years, experience. These things do not guarantee an enlarged viewpoint, a broader understanding, a more comprehensive perspective. There are many seasoned, intelligent, educated, elderly people who, sad to say, fail to exhibit largeness of perspective. Sin has not been conquered, hurts fester within their soul, self concerns and pet causes still rule their hearts.
God Almighty alone sees the end from the beginning; He viewed a vacuum - nothingness - and spoke worlds into existence. He alone comprehended sin, loved in spite of sin, and made a way to redeem us from sin and its consequences. His is the perspective we all need.
And it's available to us. The Word is ours to feast upon. The Spirit indwells those who believe and teaches us all things. He has not left us as orphans, but has made a way for us to grow in grace, spiritual maturity, and eternal perspective.
The fear of the LORD is the beginning of wisdom, And the knowledge of the Holy One is understanding. Proverbs 9.10
