That they may see your good works and glorify your Father who is in heaven.
We who are Evangelicals have are have very tenuous relationship with good works. We learn that nothing is so deceiving than believing in our own good works, for all our righteousness comes from the Lord Jesus. Very early in my childhood I learned that all my good works were as filthy rags, for I was brought forth in iniquity and in sin did my mother conceive me.
At age 59, I know I'm not much. But I also know that every day I can and I do make choices that are God honoring. I don't just let go and let God. But by God's help, by the amazing understanding that God loves me and desires for me to be good, I can do good—real good; genuinely kind acts that others are effected by, for good.
Every day I observe other Believers pressing on in good deeds. I know that this causes me to glorify our Father in heaven.
