But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption:
1 Corinthians 1:30 (KJV)
Jesus has become our wisdom, our righteousness, our sanctification, and our redemption. And so let us remember to not look to ourselves, but to Jesus. Being in Christ means that He has become our sufficiency unto whatever need may arise.
