I find that seeing a picture of a positive future outcome can help me do hard things that I might not otherwise do. For instance, seeing a picture of a skinnier 'more in shape' me motivates me to get back in the gym even though I have failed to go for 3 weeks straight. Thinking of a happier time in a relationship that has wandered can bring me to a desire to reconcile.
This can be true spiritually. When a failure in this are has caused dire consequences we need only to recognize that if we change and turn that circumstances can be turned in time. For example, Saul turned and look at the results! “The church then had peace throughout Judea, Galilee, and Samaria, and it became stronger as the believers lived in the fear of the Lord. And with the encouragement of the Holy Spirit, it also grew in numbers.” Acts of the Apostles 9:31 NLT
What if failure didn't stop you? Would greater peace result? Would an unhealthy fear of failure turn to a healthy and reverent fear of God? Would growth occur? How about we try?
