'Spiritual' in the Bible

It is right for me to feel this way about you, because [you have me in your heart as] I have you in my heart, since both in my imprisonment and in the defense and confirmation of the good news [regarding salvation], all of you share in [His matchless] grace with me.

for I know [with confidence] that this will turn out for my deliverance and spiritual well-being, through your prayers and the [superabundant] supply of the Spirit of Jesus Christ [which upholds me].

so that I may attain to the resurrection [that will raise me] from the dead.

The grace of the Lord Jesus Christ be with your spirit.
