'Indeed' in the Bible

But you are not in the flesh but in the Spirit, if indeed the Spirit of God lives in you. But if anyone does not have the Spirit of Christ, this person {does not belong to him}.

and if children, also heirs--heirs of God and fellow heirs with Christ, if indeed we suffer together [with him] so that we may also be glorified together [with him].

Indeed, [he] who did not spare his own Son, but gave him up for us all, how will he not also, together with him, freely give us all [things]?
