"So that you may live a life worthy of the Lord and please him in every way; bearing fruit in every good work, growing In the knowledge of God." NIV
"That ye might walk worthy of the Lord unto all pleasing, being fruitful in every good work, and increasing in the knowledge of God."KJV
How do we live a life worthy of the Lord? It certainly cannot be within our own power, as we are human and imperfect. It cannot be by what we feel 'living worthy' means, because we are all so different in our beliefs of what that might be, there would be no unity among us. Just as it says in the preceding verse, we pray to be filled with the knowledge and wisdom of the Lord through His Spirit, so that we will in obedience to that, walk worthy (v.9). It's the only way. We have access to it. Let us walk in it and please our Lord.
Heavenly Father, we thank You that You have provided the way for us to walk worthy in Your presence. Help us to be disciplined and obedient so that we will walk as You want us to walk. We ask in Jesus' name, Amen.
