How do we actually DO this? The only way is by His grace. We know that we need to know His word, we need to believe it in our hearts and confess it with our mouths - but how do we walk with and in Christ?
I think we need to stop over thinking it - the definition of a Christian is a follower of Christ - someone who walks with Him and in HIS Way. It’s all about being His disciple. That means we discipline ourselves and some of our desires to get in line with God’s desires - that is like doing His will on earth as it is in heaven.
Our desires can come from God and His will and purpose for us, they can also come from our selfish nature and from the enemy. When we walk in Him, it’s easier to discern this and He gives us the grace we need to make the best choices. Having a spirit of thankfulness and praise helps a lot too - so we don’t succumb to envy and take our eyes off of the Lord.
