Psalm 81: The Lord our God has heard us, relieved us, freed us, rescued us and answered us (vv. 6-7). He now wants us to listen to him (vv. 8,13). Listening to Him involves both cost and blessings. The cost is we cannot walk in our own ways (v. 13). The blessings are finest of the wheat and honey from the rock (v. 16).

Psalm:81 God would richly provide and satisfy those who listen and obey Him.

Psalm 81: “Sing for joy to God our strength; shout aloud to the God of Jacob!But you would be fed with the finest of wheat; with honey from the rock I would satisfy you.””
‭‭Psalm‬ ‭81:1, 16‬
If we listen and obey Gods commands, he will bless us abundantly and fulfill with our needs.

13 ஆ, என் ஜனம் எனக்குச் செவி கொடுத்து, இஸ்ரவேல் என் வழிகளில் நடந்தால் நலமாயிருக்கும்! – in the places of ‘என் ஜனம்’, ‘இஸ்ரவேல்’, I substitute ‘கிறிஸ்தவன்’ and read.
– It looks like we are in the period where God says as in v11. We need to pray that this trend changes. While praying for this, I would check and ensure I am in faith!

Psalm 81 -(v12) So I let them go after the stubbornness of their heart, that they might walk in their own counsels.
-He guides us only when we obey to Him. If we don’t obey, the Spirit of the God will not be with us. If the Spirit of the God is not with us, the spirit of the evil will conquer our heart, that will lead us to all the deceitful things.
