Which of you by taking thought can add one cubit unto his stature?
And why take ye thought for raiment [clothing]? Consider the lilies of the field, how they grow; they toil not, neither do they spin:
And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these.
Wherefore, if God so clothe the grass of the field, which to day is, and to morrow is cast into the oven, shall he not much more clothe you, O ye of little faith?
Therefore take no thought, saying, What shall we eat? or, What shall we drink? or, Wherewithal shall we be clothed?
(For after all these things do the Gentiles seek for your heavenly Father knoweth that ye have need of all these things.
But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you.
Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof. Matthew 6:27-34 (also see Luke 12:26-34)

We desperately need the LORD GOD's / The Lord Jesus Christ's clothing of Righteousness through real belief in & obedience to/ love for HIM to enter Heaven.  This is fact, not fiction & infinitely more relevant that material clothing which shall pass away. 

Isaiah 61:10
I will greatly rejoice in the LORD, my soul shall be joyful in my God; for he hath clothed me with the garments of salvation, he hath covered me with the robe of righteousness, as a bridegroom decketh himself with ornaments, and as a bride adorneth herself with her jewels.

Psalm 132:9
Let thy priests be clothed with righteousness; and let thy saints shout for joy.

Isaiah 54:17
No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn. This is the heritage of the servants of the LORD, and their righteousness is of me, saith the LORD.

Jeremiah 23:6
In his days Judah shall be saved, and Israel shall dwell safely: and this is his name whereby he shall be called, THE LORD OUR RIGHTEOUSNESS.   


Judah & Israel parabolically refer to the entire body / the eternal church of / in the Lord Jesus Christ from all mankind over time who shall receive GOD's pardon through The Lord Jesus and shall enter Heaven, by HIS mercy alone. All others shall not.
