Not elaborate altars. Simple altars. Altars acknowledging who God is. Not the intricate work of our hands. Not altars beautiful to look upon. Simple altars where God is acknowledged and worshiped. That is the kind of altar He blesses.
Under the new covenant, how do I build an altar? I present my body, my life, as a living sacrifice. I don’t offer a dead sacrifice. I offer a living one. The Lord makes it holy and acceptable. Not me. My righteous deeds are as filthy rags in His sight (Isaiah 64:6).
God makes me holy by the sacrifice of His Son on the cross. I humbly present myself, submit to Him, and ask Him to transform me. He does the work—not because of me, in spite of me.
We are unable to save ourselves. It is the work of Christ!

Here is a trustworthy saying that deserves full acceptance: Christ Jesus came into the world to save sinners—of whom I am the worst. (1 Timothy 1:15)
Therefore, I urge you, brothers and sisters, in view of God’s mercy, to offer your bodies as a living sacrifice, holy and pleasing to God—this is your true and proper worship. (Romans 12:1)
