The great mistake made by most of the Lord's people!

(Arthur Pink, "The Doctrine of Sanctification" 1937)

"You are complete in Him!"
Colossians 2:10

The poor Christian, conscious of his weakness, his ignorance, his poverty, his vileness — is sorely tempted to be envious of others, for they seem to have "more than heart could wish" — while the longings of his heart are denied him, and that which he pursues so eagerly continues to elude his grasp.

God's children are oppressed, sorely oppressed . . .
  by their indwelling corruptions,
  by their innumerable failures,
  by the hidings of the Lord's face,
  by the accusations of Satan,
  over the workings of unbelief,
  over the coldness of their hearts,
  over the insincerity of their prayers,
  over their vain imaginations.
The great mistake made by most of the Lord's people is in hoping to discover in themselves, that which is to be found in Christ alone.

"By His doing you are in Christ Jesus, who became to us wisdom from God, and righteousness and sanctification, and redemption." 1 Corinthians 1:30
