There is an old adage that says, "Don't bite off more than you can chew". It's wise not to take on more responsibilities than we can handle. At some time, however, we will likely feel overwhelmed by the size and difficulty of a task we have agreed to do. This can happen even in our walk of faith in Christ when our commitment to God seems too much to bear.
But, the Lord has an encouraging word for us when our confidence wavers. The writer of Hebrews urged his readers to recall the courage they demonstrated during the early days of their faith (10:32-33). Despite public insults and persecution, they aided believers in prison, and they joyfully accepted the confiscation of their own property (vv. 33-34). With that in mind, he says, "Therefore, do not cast away your confidence, which has great reward. For you have need of endurance, so that after you have done the will of God, you may receive the promise" (vv. 35-36).
Our confidence is not in ourselves but in Jesus and His promise to return at just the right time (v. 37). It is God's power that enables us to continue in our journey of faith. Recalling the Lord's faithfulness in days past stirs our confidence in Him today. Trusting God's faithfulness stirs up our own confidence. So, be confident! God has your back.
