James 2:18

2:18 But someone will say, “You have faith and I have works.” Show me your faith without works and I will show you faith by my works.

Galatians 5:6

5:6 For in Christ Jesus neither circumcision nor uncircumcision carries any weight – the only thing that matters is faith working through love.

Hebrews 11:17-19

11:17 By faith Abraham, when he was tested, offered up Isaac. He had received the promises, yet he was ready to offer up his only son. 11:18 God had told him, “Through Isaac descendants will carry on your name,” 11:19 and he reasoned that God could even raise him from the dead, and in a sense he received him back from there.
