* Signs can help people remember something. This is often something that was promised.
1. Rainbows are signs to remind people that God promised not to flood the world again (see: Genesis 9:12-13).
1. Circumcision was a sign of the covenant between God and Abraham. God promised to give Abraham and his descendants the promised land (Genesis 17:11-14).
1. The Bible also talks about signs and wonders. These are miracles that God does or a person does by God’s power. These miracles prove that what God says is true (Acts 2:22; 15:12; 2 Corinthians 12:12; Hebrews 2:4).
