God is pleased by Christians who walk with him in a worthy way. “Worthy” means to honor (axios). To honor God is to reflect the sweetness of knowing him to others.
God supplies all we need to walk with him. The power and wisdom (1:9) come from God.
The good works God calls us to are the result of his work in our lives, not the basis of our acceptability to him. Works are demonstrations of saving faith, not the way we find salvation. In 1:12 it is the Father who qualifies the true believers to share in his inheritance.
The Christian life is a “walk.” It is not a sprint, but more like a marathon, a “long obedience in the same direction.” Walking is something we attend to each day. We are moving, even slowly, down a path with God. Let’s enjoy the moment! And we should note that the change that occurs along the way comes over time, as we learn to trust God each day. The crucial transformations this paragraph discusses don’t come through one-time experience, but are carved into our character like a beautiful rock formation is shaped by the sea. It requires knowledge and wisdom (1:9). These are skills we develop through months and years of learning to practice biblical truths in practical ways. To be “filled” (pleroo, 1:9) with knowledge is to experience the fullness, the thorough effect of truth in our lives. God’s truth is holistic, it reaches into every part of our being, and that is how we are changed by it (see Deuteronomy 6:4-9).
What does it mean to “bear fruit”? Jesus taught that his disciples were to “bear fruit” as proof that they were his disciples (John 15:8). Our lives are a stewardship, given to us by God to glorify him.
To walk in a worthy way, we must be changed. It is not something we can do on our own, but it is the result of God’s work in our inner lives. What does this change look like? 1:11,12 identifies four characteristics necessary to walk with God over the long course of this life:
Endurance (1:11). This is the ability to press on even when it is difficult; to not give up. Think about God’s word to Jeremiah, “If you have run with men and they have tired you out, then how can you compete with horses?” (Jeremiah 12:5).
Patience (1:11). Change will come, but we must have the long view. Patience is both a fruit of the Spirit (Galatians 5:22) and a crucial aspect of love, the first quality Paul refers to in defining agape love (1 Corinthians 13:4).
Joy (1:12). Joy is the inner experience of God’s goodness. It is the personal knowledge that God is a God of blessing, that he is always present, that no matter what may happen, God is at work in our lives for our good and his glory.
Gratitude (1:12). Gratitude shows that we truly understand the goodness and mercy of God. That by his grace we share his inheritance. Viewing each day as an undeserved gift from God keeps our perspective where it needs to be. Rather than being chronically disappointed, angry, or distracted, gratitude keeps us seeing our lives from God’s perspective.
