Joshua had to rebuke the children of Israel because they failed to possess what God had given them to inherit. Joshua 18:3 says, “…How long will you neglect to go and possess the land which the Lord God of your fathers has given you?”
This begs the question: what have I neglected to possess that the Lord has given me? Possess is to take ownership. In verse 4 he said he would send 36 men to go through the land, survey it according to their inheritance.
Jesus possessed gladness because He loved righteousness. He loved the Father and chose to follow His will. John 5:19-20 says, “…the Son can do nothing of Himself, but what He sees the Father do; for whatever He does, the Son does in like manner. For the Father loves the Son, and shows Him all things that He Himself does…”
Here are David’s words. Psalm 40:8 says, “I delight to do Your will, O my God, and Your law is within my heart.” It echos the words of Psalm 100:1-2. “Make a joyful shout to the Lord, all you lands! Serve the Lord with gladness; come before His presence with singing.”
Isaiah 35:10 is a verse about Israel coming into Zion. We can apply it for ourselves. It is present and future. It says, “And the ransomed of the Lord shall return, and come to Zion with singing, with everlasting joy on their heads. They shall obtain joy and gladness, and sorrow and sighing shall flee away.”
Suppressing the truth through unrighteous thoughts will cause inward sorrow and sighing. Do you ever sigh? However, possessing righteousness will empower us–making it our own through our thoughts, purpose, and actions. The oil of gladness on us will affect those around us. Joy and gladness is the language of His Kingdom.
