Father of faith.

**The reasoning** Abraham is universally known as the "Father of Faith" across Judaism, Christianity, and Islam. Why? Because God called him to leave his homeland (Ur) with nothing but a promise — no proof, no map, just trust. Genesis 12 records God's covenant with Abraham: "I will make you into a great nation." Abraham believed God's promise even when it seemed impossible (he and Sarah were old and childless). His willingness to obey God without seeing the outcome first — especially in the test with Isaac — made him the ultimate example of faith. Romans 4:16 and James 2:23 confirm this title, calling him "friend of God" and "father of all who believe." **Why the wrong options tempt you** - **Adam**: First man, yes — but known for disobedience (eating the forbidden fruit), not faith. - **Noah**: Man of great obedience (building the ark), but Abraham's covenant established the lineage of faith. - **Moses**: Great leader and lawgiver, but he followed Abraham's covenant line. **Quick takeaway** Abraham = believing God's promises when the situation looks impossible — that's why he's the Father of Faith.
