JMNT(i)
16 The same Spirit (or: spirit; or: The Breath-effect Himself; or: This very attitude)
is constantly witnessing together with our spirit (is continuously bearing joint-testimony to our spirit; is habitually co-witnessing for our spirit; is progressively adding confirming testimony and evidence in our attitude)
that we are, and continuously exist being, God’s children (ones born of God; children from God [not of the child-escort {
Gal. 3:24}], by natural descent).
17 Now since children (or: Yet if ones born by natural descent),
also heirs (possessors and enjoyers of an allotted inheritance; those who hold sway over the allotted portion):
on the one hand, God’s heirs, on the other, Christ’s joint-heirs (or: indeed possessors and enjoyers of an allotment pertaining to God and from God, yet possessors and enjoyers together in an allotment pertaining to Christ and belonging to Christ)
if so be (or: provided)
that we are continually affected by sensible experiences together – feeling together; receiving impressions, undergoing passion or suffering together – to the end that we may also be glorified together (or: can be given a shared appearance; would together receive a manifestation of that which calls forth praise; should be given a joint-approval and a joint-reputation; may be thought of and imagined together [in covenant relationship]).
18 You see, I have come to a reasoned conclusion (or: I am reckoning and logically considering)
that the effects of the sensible experiences – sufferings, impressions, passions or feelings – of the current season (or: of the situation fitted to the present time) [
are]
not equivalent (do not balance the scales; are not of equal value or worth), [
being]
face to face with the glory (or: [are] of insufficient weight when put in balance to the manifestation which calls forth praise as well as the reputation and good opinion)
which is progressively about to be disclosed unto us, and for us (or: unveiled into our midst; revealed to and [enter] into us).
