Walk by Faith and Be Renewed in Spirit

New Mercy for a Weary Heart

To walk by faith and be renewed in spirit is not always easy. We are called to walk by faith and not by sight (2 Corinthians 5:7), but life can leave us tired, uncertain, and weighed down. Still, Christ meets us in that place. As we trust Him, lean on His promises, and keep our eyes on Him, He renews our spirits day by day.

Paul reminds us not to lose heart, even when our bodies grow weak and life feels heavy. Though outwardly we may be wearing down, inwardly God is renewing us day by day. This is one reason we can walk by faith and be renewed in spirit, even when the present struggle feels hard. What we suffer now is temporary, but God is using it to prepare an eternal glory far greater than anything we can see in the moment (2 Corinthians 4:16–17).

That is why Lamentations 3:22-24 brings such comfort. It reminds us that we are not consumed because the Lord is merciful. His compassion does not run out, and His mercy is new every morning. Yesterday may have carried failure, disappointment, or regret, but it does not get the final word. God’s mercy does. We receive it not because we have earned it, but because He is good, kind, and faithful.

Trusting God by Faith: A Biblical Example

That same kind of faith shows up in the Gospel of John, where Jesus invites a desperate father to trust His word before he sees the miracle.

A beautiful picture of this kind of faith appears in the story of the nobleman whose son was sick. He came to Jesus, hoping the Lord would go with him to Capernaum and heal his child. But Jesus did something unexpected. He said, “Go your way; your son lives.” That was all the man had to hold on to: the word of Jesus.

And that was enough. The nobleman believed what Jesus said and started walking home. Before he ever saw the healing with his own eyes, he chose to trust the Lord’s word. On the way, his servants met him with the news, “Your son lives!” When he learned the healing happened at the very hour Jesus spoke, he knew the word of the Lord was true.
