When you made Jesus Christ the Lord of your life, Colossians 1:13 says you were delivered from the power of darkness. The word power is literally translated “authority.” You have been delivered from the power, or authority, of darkness and placed into God’s kingdom. Jesus said, “All power is given unto me in heaven and in earth. Go ye therefore...” (Matthew 28:18-19). That power was given to you as part of your inheritance in Christ Jesus. You have entered into this position of authority because you are in Him.
When you see in the Word that you are in Christ Jesus, that you are in Him, then confess it with all your heart. Then you will be strong, standing in a point of authority and operating in your inheritance in Him. As you do this, the power of God will always be available to work in your behalf. Praise God!
