All may look well, perfect & complete, yet if there is some imperfection unseen & incomplete, that would lead to disqualification, for judging by what is seen is not how God does things, for there is nothing hidden from Him, for the awesome Lord is powerful to look through everything as they actually are.
"Pursue peace with all people, and holiness, without which no one will see the Lord:" Hebrews 12:14 (NKJV)
Imagine a situation where a person is walking on the road wearing a pure white dress, his attempt all through the journey should be to avoid the dress getting stained by the innumerable opportunities available on the way and he needs to be more careful when he is walking through a passage or lane filled with dirt, filth and everything available to make his dress dirty.
Today, we are living in an age where sin is easily available, many countries, societies and groups of people have indulged themselves in sinful activities to such an extent that continuing in them has become the normal trend amongst them, earlier when people could call on God and were dedicated to Him in the little they had, God blessed them and they had great contentment, peace and solace, however now with more of everything, the people have forgotten God and thus discontentment, hatred, strife, lack of peace and many other unblessedness rule their hearts and lives.
God has not changed all these days, He is the same powerful to redeem, ready to forgive and willing to restore us always.
With God's help it is perfectly possible to move ahead in the blessedness and sanctity that God has desired of us.
Take note of this, the world will pull us to sin and it may also present a blessed future with the stains of sin, however we have to pursue/decide/yearn for holiness, failing which we will never be able to see our blessed Lord and for such who sin and love to live in sin is reserved the eternal hell, yet for those who pursue holiness and do it with God's help is reserved the eternal heaven and blessedness with the Lord...the choice is our's, we have to pursue it, we have to maintain our sanctity.
