God does what no one else can do
The Bible uses the word wonders for God's extraordinary works, especially acts that reveal his character and power. The psalmist says God is the one who performs wonders and makes his strength known among peoples (Psalm 77:14). This is not simply saying that God is surprising. It means his deeds show that he is unlike any human ruler, idol, or force of nature.
Psalm 77 comes from a painful place. Asaph is troubled and struggling to feel comforted, yet he deliberately remembers God's earlier works. God being a God of wonders does not mean life is always easy or instantly explained. It means suffering does not have the final word over God's faithfulness.
Thou art the God that doest wonders: thou hast declared thy strength among the people.
His wonders reveal his mercy
Many of God's wonders in Scripture are acts of rescue. He delivered Israel from Egypt when they could not free themselves, and the Psalms remember the signs he did there (Psalm 78:12). The point was never entertainment. God acted to keep his covenant promises and to bring an oppressed people out of slavery.
The same pattern appears in the repeated praise of Psalm 136: God alone does great wonders because his mercy endures. His power is not cold or distant. In the Bible, God's mighty acts are joined to his steadfast care for people.
To him who alone doeth great wonders: for his mercy endureth for ever.
Jesus' signs point to God
Jesus also did works that caused people to marvel: healing the sick, feeding hungry crowds, calming the sea, and raising the dead. John calls these deeds signs because they point beyond the event itself. When Jesus turned water into wine at Cana, the sign displayed his glory and led his disciples towards faith (John 2:11).
So Christian faith is not built on chasing unusual experiences. Wonders are signposts. They direct attention to Jesus, to his authority, and to the good news that God has come near. Even the greatest signs in the Gospels call for a response of trust, not just curiosity.
Wonder can grow in ordinary days
God may still act in remarkable ways, and Christians differ on how they describe particular miracles today. But Scripture also teaches us to see his greatness in what is always before us. The heavens declare God's glory, and the ordered world speaks of its Maker (Psalm 19:1).
You don't have to manufacture a dramatic moment to know God. Start by noticing his faithfulness, bring him your real needs in prayer, and read the stories of his works in Scripture. When you remember what God has done, wonder becomes more than a feeling. It becomes a reason to trust him.
The heavens declare the glory of God; and the firmament sheweth his handywork.
