How do we know God can still perform miracles today?

The assurance that God can perform miracles today is rooted in the truth that He is immutable, the same yesterday, today, and forever. The testimonies of historical revivals and miraculous conversions serve as a precedent, encouraging believers to have faith in God's continued work. As C.H. Spurgeon emphasizes, what God has done in the past is not just history but a prophecy of what He can and will do again. When the church earnestly seeks God in prayer and faith, expecting His intervention, great things can still occur, echoing the miraculous accounts found in scripture.
