'Co heirs' in the Bible

Now if we are children, we are heirs heirs of God and co-heirs with the Messiah if, in fact, we share in his sufferings in order that we may also share in his glory.

which in other generations was not made known to men, as it is now revealed to his holy apostles and prophets by the Spirit; that the Gentiles should be co-heirs,

that the gentiles are co-heirs and of the same body and joint partakers of the promise in Christ Jesus through the gospel,

By faith he sojourned in the land of promise, as a foreign land, dwelling in tents with Isaac and Jacob, the co-heirs of the same promise.

Ye husbands, in like manner dwell with them discreetly, putting respect on the dear woman as being the weaker vessel, and as co-heirs of the grace of life, so that your prayers may meet no interruption.
