"And God raised us up with Christ and seated us with Him in the heavenly places in Christ Jesus." (Ephesians 2:6, BSB)
At a big wedding, the host's family hurries to find you a seat. "Please, sit near the front." You don't earn it. A place has been kept for you before you walk in. Paul says God has done that for us. He "raised us up with Christ and seated us with Him." Not "will seat". Seated. The seat matters. Under the old order, the priests never sat down. There were no chairs in the tabernacle, because their work was never finished. "Every priest stands daily at his service, offering again and again the same sacrifices" (Hebrews 10:11). Standing meant unfinished. That was the shadow. Then Christ finished it and "sat down at the right hand of God" (Hebrews 10:12). Sitting means done. And Paul says you're seated with Him, in that same place of rest. Notice how Ephesians is built.
