'Truth' in the Bible

For the hope which is laid up for you in heaven, whereof ye heard before in the word of the truth of the gospel;

Which is come unto you, as it is in all the world; and bringeth forth fruit, as it doth also in you, since the day ye heard of it, and knew the grace of God in truth:

the truth which has been kept secret from all ages and generations, but has now been revealed to His people,

to whom it was His will to make known how vast a wealth of glory for the Gentile world is implied in this truth--the truth that 'Christ is in you, the hope of glory.'

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.

And pray at the same time for us also, that God may open for us a door for preaching, for us to tell the truth concerning Christ for the sake of which I am even a prisoner.
