1 Corinthians 1:5
…that in everything you were enriched in Him, in all speech and all knowledge,
All who are “in Christ” have had their lives enriched in every way. The word enriched means to make rich or to fully furnish. Once you are born again you have all you need because you have God. To walk in the knowledge of what God has made available to you comes by speaking what is revealed in His Word. It is through His Word that we come to know what we have been given.
When you go to the written Word of God, primarily the epistles for these are the letters that reveal who we are in Christ, what we have in Christ, and what we can do through Him, and you begin to confess that over your life; then the knowledge of what you have been given will begin to become real to you. As it does you begin to lay hold of what God has enriched your life with.
For example scripture teaches us that we are more than conquerors through Him who loves us. Begin to confess this over your life. You may not feel like you are more than a conqueror, but we walk by faith not by sight. The more you confess what scripture says about you the more real it will become to you. Begin to confess who you are, what you have, and what you can do in Christ Jesus and you will begin to rise up into all God has enriched your life with through Jesus Christ.
