“Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new”
(2 Corinthians 5:17).
Christianity isn’t ‘foundationally’ about what you do but about who you are. ‘Doing good’ isn’t what makes you a Christian. You are a Christian because you believe in Jesus, who in response to your faith, has made you a new man with new desires by His Spirit. In other words, instead of the popular notion: “I must do good to be a Christian,” the truth is, I can do good because I am a Christian.
Christianity isn’t a lifestyle, but a life that has a lifestyle. It is a new nature you receive when the Holy Ghost comes to dwell in you. However, when you receive the life of God, your lifestyle is influenced for the better. A righteous lifestyle is the result, not the prerequisite for being a Christian. Your lifestyle proves that you have received the life of God, but it isn’t the life of God in itself.
Friend, there is a huge difference between striving for righteousness ‘to be’ (or keep being) a child of God and striving for righteousness ‘because’ you are a child of God. Recognizing who you are in Christ empowers you to effortlessly produce fruits of righteousness, consistent with the nature of righteousness that you have received as a gift.
I have the life of God in me. I am a new creature in Christ. God works in me to do His good pleasure. Halleluyah.
