Some questions to ask of Ephesians 4:22-24 (and context) - preferably with a friend, preferably with some personal struggles in mind:
22You were taught, with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires; 23to be made new in the attitude of your minds; 24and to put on the new self, created to be like God in true righteousness and holiness.
What are the desires of your old self? List them in as much detail as possible.
How are they deceiving? What do they promise? Why is that attractive? How is it a lie?
How are they corrupting? How are they affecting you? Describe their ugliness to the Lord and others.
Spend some time feeling the power of these desires, lies and corruptions. Realize that you cannot redeem yourself.
Now consider - what has happened to this old self? (cf Rom 6:6)
Meditate on this: Christ loves and redeems not your new self but your old self - in all its lusts, lies and ugliness.
Meditate too on the oldness of this former self - crucified with Christ.
Describe the new self.
Are you the one to 'create' this new self? Where does it come from?
How is the Lord making you new in the attitude of your minds?
How is this new thinking different to your old thinking (v17-19)
In what ways can you meditate on this new 'truth in Jesus' (v21)?
Come up with opposing statements to counter the desires and promises of the old self.
