Joy comes from knowing who you are in Christ and trusting in Him. To trust in Him is to trust in His grace. For you, brethren, have been called to liberty; only do not use liberty as an opportunity for the flesh, but through love serve one another. For all the law is fulfilled in one word, even in this: "You shall love your neighbor as yourself." But if you bite and devour one another, beware lest you be consumed by one another! I say then: Walk in the Spirit, and you shall not fulfill the lust of the flesh. For the flesh lusts against the Spirit, and the Spirit against the flesh; and these are contrary to one another, so that you do not do the things that you wish. But if you are led by the Spirit, you are not under the law. Galatians 5:13-18 NKJV How do you kill the sinful nature?...‚Ä¶ How do you get to know Christ?
