Mat 6:33  "But seek first His kingdom and His righteousness, and all these things will be added to you.

Col 1:13  For He rescued us from the domain of darkness, and transferred us to the kingdom of His beloved Son,

1Co 1:30  But by His doing you are in Christ Jesus, who became to us wisdom from God, and righteousness and sanctification, and redemption,

2Co 5:21  He made Him who knew no sin to be sin on our behalf, so that we might become the righteousness of God in Him( at the point of salvation).

 Mt 6:33 says to seek His kingdom but Col 1:13 says we (believers) are already there, Mt 6:33 says to seek His righteousness but 1Cor 1:13 & 2Cor 5:21says we (believers) already have it.  Would a sound person seek his wrist watch when it's on his arm?
