We should be growing and changing all the time as we seek Christ. The more we know Him the more we see in ourselves that needs work. He is the One Who does the work in us, all we have to do is confess it and then He goes to work cleansing us.
1 John 1:9
"9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness."
We have no excuse to fail because it is not our own effort, it is our confession and God's work in us.
Ephesians 2:10
"10 For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them."
We can never legitimately use the excuse that we are not perfect, we can always confess our flaws and ask for cleansing. Then we can ask the Lord to reveal anything in us that we cannot see about ourselves.
When we are born-again we know we are not perfect but we are not comfortable in that imperfection because we are always looking at Christ and comparing ourselves with Him.
When we compare ourselves with others we will always see someone who is worse than ourselves. But when we compare ourselves with Christ we know there is more work to be done in us.
No one is better than someone else and no one is worse than someone else, everyone is "desperately wicked", it is only Christ Who is Good!!!!! When we know this we have no pride left in us, no boasting and no comparing ourselves with others.
Humility comes when we know only Christ is good. We have no need to impress anyone because there is nothing good in us except Christ, because we know this we walk in joy and peace without the inward pressure to perform for others. It is only God we wish to please. Hallelujah!!!!!
