38 Now it happened as they went that He entered a certain village; and a certain woman named Martha welcomed Him into her house. 39 And she had a sister called Mary, who also sat at Jesus’ feet and heard His word. 40 But Martha was distracted with much serving, and she approached Him and said, “Lord, do You not care that my sister has left me to serve alone? Therefore tell her to help me.” 41 And Jesus answered and said to her, “Martha, Martha, you are worried and troubled about many things. 42 But one thing is needed, and Mary has chosen that good part, which will not be taken away from her.” Luke 10
Note: Martha had a physical relationship with Christ, in serving Him, while Mary had a Spiritual relationship by hearing and worshiping Him. Martha was doing a good thing, but it was not the best thing. We learn that one can be very much involved in the Work of the Lord, and little involved in Worship of the Lord. However, the Lord is much more concerned about the Worker than the Work. If the Worker is right, the Work will be right as well!
There are many hidden traps and snares (the tree of the knowledge of good and evil) in this life due to the fall of Adam. This is why the scriptures says, "There is a way that seems right to a man, but the end thereof are the ways of death (Proverbs 14:12, 16:25)."
The only way the Believer can walk in the Spirit is by placing and maintaining their Faith exclusively in Christ (who He is) and the Cross of Calvary where the victory was won (what He has done), i.e., The Finished Work, i.e., The Blood of Jesus. (Romans 8:2)
If it's done in the flesh, it will consume the person, i.e., "the bush"; however, if it's done by the Power of the Holy Spirit, the bush will burn and not be consumed (Exodus 3:2, Romans 8:2).
