Isaiah 1:13 Stop bringing meaningless offerings! Your incense is detestable to me. New Moons, Sabbaths and convocations - I cannot bear your worthless assemblies.
One of the things we see from time to time is how God told the people through the prophets that their offerings were worthless!
God does not look at the physical act of offerings or sacrifices…
God looks at your heart and what you actually feel about any offering you may bring forward!
