Yes. Both are true since we live in the already not yet tension, where Christ is reigning but the kingdom has not yet been delivered back to God. Where we are redeemed from the penalty of sin, and find victory over the power of sin, but not yet removed from the presence of sin. Where the life of God in us is sinless but in tension with the flesh that is clearly still capable of sin.

Clustering verses around one or other of these polarities doesn't prove the point, it just highlights the polarity. There is a day when that tension will be removed. Meanwhile, we groan inwardly for it and continue to strive against sin.

God sees me sinless in Christ because He sees me outside of time, with the completed redemption already applied. It's as good as done for me to be eternally in his presence in the new creation. However, I'm not able to see from that perspective. I'm firmly bound within time, and therefore limited to the present moment where my struggle with sin is real. What to God is a momentary detail that's already been dealt with, is to me my present reality in which I struggle so that Christ may be formed in me.

With a little humility, these polarities become occasions to glorify God rather than strive over incomplete positions. Which I think is the point of Sola Dei Gloria.
