He wants your heart!
Verse 13, “Inasmuch as these people draw near with their mouths and honor Me with their lips, but have removed their hearts far from Me, and their fear toward Me is taught by the commandment of men.”
God is not impressed with our “praise-the-Lords,” our yard signs, or our involvement in religious activities. Neither is He impressed with our Bible knowledge or our pious-sounding prayers.
Many of those things are good. We should have an attitude of praise toward God. We should be willing to proclaim our faith. We should be faithful to learn more about God’s Word and spend time with Him in prayer. But none of that matters to Him, unless He first has our hearts.
