'Attain' in the Bible

The unspiritual man rejects the things of the Spirit of God, and cannot attain to the knowledge of them, because they are spiritually judged.

yes, to attain to a knowledge of the knowledge-surpassing love of Christ, so that you may be made complete in accordance with God's own standard of completeness.

in the hope that I may attain to the resurrection from among the dead.

in order that their hearts may be cheered, they themselves being welded together in love and enjoying all the advantages of a reasonable certainty, till at last they attain the full knowledge of God's truth, which is Christ Himself.

for God had provided for them and us something better, so that apart from us they were not to attain to full blessedness.
