'Thing' in the Bible

Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ:

Just one thing: Live your life in a manner worthy of the gospel of Christ. Then, whether I come and see you or am absent, I will hear about you that you are standing firm in one spirit, with one mind, working side by side for the faith that comes from the gospel,

fulfil ye my joy, that ye may mind the same thing -- having the same love -- of one soul -- minding the one thing,

who, although He existed in the form of God, did not regard equality with God a thing to be grasped,

Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before,

Let us therefore, as many as be perfect, be thus minded: and if in any thing ye be otherwise minded, God shall reveal even this unto you.

Nevertheless, whereto we have already attained, let us walk by the same rule, let us mind the same thing.

Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
