Biblical faith, as demonstrated through Abraham's journey, is not blind trust but rather confidence grounded in God's proven character. At nearly 100 years old, Abraham believed God's promise of fathering nations, not by ignoring reality but by trusting God's power to overcome impossible circumstances. His faith grew stronger through worship and complete conviction in God's ability to fulfill promises. This kind of faith operates by basing present confidence on God's past faithfulness while bringing future certainty into present reality.
