I have been installing new windows in the parsonage.  We replaced the windows in the living room, dining room, kitchen, and bathroom with plans to replace the bedroom and office windows next year.  Of course our little boys were all excited about the project.  They got to watch daddy work and they even got to crawl up and down the ladder outside.
-
They definitely noticed the change as our house was renewed by having the old windows taken out and the new ones put in.  It reminds me of Ephesians 4:22-24, “That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts; And be renewed in the spirit of your mind; And that ye put on the new man, which after God is created in righteousness and true holiness.”
-
We could see a difference between the old windows and the new ones just by how they looked, but the real difference is in how they perform.   The new windows open and shut easily whereas the old ones did not. Then come next winter we expect them to be much less drafty than the old ones.
-
The Ephesians passage is not about windows, but about believers in Christ.  Like the windows, righteousness and true holiness is not as much about how it looks on the outside as how it actually performs.
-
Consider the differences listed in the Ephesians passage:  In the next verses we are told not to lie but instead to speak the truth.  Then we are told not to lose control when angry, but instead let the go of wrath at the end of the day.   It comes down to following God instead of doing what the devil wants us to do.  That means not stealing, but instead working so that you can earn extra to give to others in need.   True righteousness and holiness means being careful that bad things don’t come out of your mouth but instead giving words of encouragement and grace.  Finally Ephesians 4 ends by instructing that instead of bitterness wrath and anger, the believer should be kind, tenderhearted and forgiving.
-
Chapter 5 of Ephesians then goes on to talk about the importance of love and thanksgiving.  It also shows how fornication, impurity, covetousness, filthy vulgar foolish talking, prostitution and idolatry are definitely not part of righteousness and true holiness.
-
These comments may be stating the obvious, but too often man tries to come up with his own list as to what righteousness and true holiness looks like while forgetting what God has already told us about it.  Fruit naturally grows on a healthy plant. 
-
A spiritually healthy Christian who is living a life close to God will naturally have fruits of the Spirit.  Ephesians 5:9 says, “(For the fruit of the Spirit is in all goodness and righteousness and truth;)”  Paul further elaborates in Galatians 5:22-23, “But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance: against such there is no law.”
-
Set aside pride for a moment and honestly evaluate if you have the fruit of the Spirit in your life.  If not, ask yourself if you are really trusting in Christ.  If you are but the fruits are still not there, then ask yourself what your focus has been.  Have you been so focused on yourself and trying to look good to others that you have actually missed out on glorifying God through natural fruit?
