“God did not send his Son into the world for him to judge the world, but for the world to be saved through him. Whoever exercises faith in him is not to be judged. Whoever does not exercise faith has been judged already […].”
~John 3:17,18

Does the Bible teach faith-based salvation?
While faith is a key component of our salvation, it is not the sole requirement.
God’s Word later explains that faith without works is useless. (Jas. 2:24,26)
What kind of works satisfy God’s standards?
To exercise true faith, we must follow in Jesus’ footsteps, sharing the message of God’s kingdom motivated by love. (Matt. 10:7,8; Jas. 2:8)
Still, we need to understand that faith and salvation are gifts from Jehovah God that are only possible through his own arrangement. (Eph. 2:8)
One Watchtower likens it to how we pray for our daily bread, and yet we understand we still have to go out and work for it.
Likewise, we have faith and work towards salvation, but left entirely on our own we could never attain it.
