Every year I make resolutions that rely on my own strength and power and every year I am surprised when I don't accomplish those things. The gospel has shown me that I am unable to accomplish anything on my own strength and power... that is why the birth, life, death and resurrection of Jesus was needed.
But God demonstrates his own love for us in this: While we were still sinners, Christ died for us. - Romans 5:8
I pray that the eyes of your heart may be enlightened in order that you may know the hope to which he has called you, the riches of his glorious inheritance in his holy people, and his incomparably great power for us who believe. That power is the same as the mighty strength he exerted when he raised Christ from the dead and seated him at his right hand in the heavenly realms, - Ephesians 1:18-20
God is desperate for us to rely on Him so that He can accomplish so much through us! He has prepared resolutions for us to accomplish if we would just rely on Him. These resolutions are bigger than going to the gym, eating healthy, meeting certain goals, etc. God has prepared resolutions that are specific to you... all you have to do is rely on Him!
