Let's jump right in at verse 5.
For through the Spirit, by faith, we ourselves eagerly wait for the hope of righteousness -(Galatians 5:5 ESV)
I want us to see all three persons of the Trinity at work in our salvation. God the father sends the Son, the Son lives a righteous life and paid the penalty for our sins in His death, burial, and resurrection, and the Spirit convicts of sin and brings us to faith and repentance. We must remember that apart from the Spirit there is no salvation. I love the Lyrics of "Praise the Father, Praise the Son:"
Praise the Father, praise the Son
Praise the Spirit, Three in One
Clothed in power and in grace
The name above all other names
This verse continues to echo the theme of the book, pointing us to justification by faith, through grace, in Christ. Our good works, church attendance, or well-intentioned decisions do not save us. Rather, it is only through faith that we are saved.
Here is a challenging question - what are we doing to intentionally strengthen our faith? Faith is like a muscle. Through periods of challenge and recovery, we can work to increase our dependence on the Lord. We can put ourselves in circumstances and situations that are prime for faith strengthening. Building relationships with our neighbors and coworkers (for the sake of the gospel) can strengthen our faith and dependence on Christ. I believe this is one of the reasons that He told us to make disciples in His great commission. It's no surprise that few Christians ever take the time to build relationships and share the gospel. It's tough, awkward, and costs us something.
