Ephesians 4:20-24 (NASB) 20 But you did not learn Christ in this way, 21 if indeed you have heard Him and have been taught in Him, just as truth is in Jesus, 22 that, in reference to your former manner of life, you lay aside the old self, which is being corrupted in accordance with the lusts of deceit, 23 and that you be renewed in the spirit of your mind, 24 and put on the new self, which in the likeness of God has been created in righteousness and holiness of the truth.
I was talking to a friend the other day who stated that his wife came successfully through back surgery. He stated that they were walking down the hallway the day after the surgery and he knew she was no longer in pain because her walk had changed. She had previously been in so much pain that it affected the way that she walked. Now she was free from pain and walking differently. How should a Christian walk (live) after faith is placed in the Savior? Should a person life differently after salvation? Paul instructs us in a rather pointed manner that our walk should not be as the old self but the new life in Jesus, which is after the Lord and His holiness. If you were to continue to read this chapter then you would read some practical ways in which Paul instructs us and that should be evident in our lives. We must speak truth and not allow our speech to even have a hint of falsehood (v25). We need to bridle our anger and not allow it to lead us to sin, which is exactly where the devil desires for us to live (v26). A person must not be dishonest and steal from others, which could be blatant stealing or dishonest business practices but sharing with those who do not have (v28). The words of our speech ought to be so changed that they are used for edification rather than destruction (v29). And finally, we should be treating people with the same love and forgiveness that Jesus has given us (v32). How is your walk? Does it resemble your old self or your new life in Christ Jesus? A new walk is the greatest witnessing tool. The world needs to see the change in our lives so that they will understand the power and grace of our Lord and know that they need Him.
