Jesus said many things. The main one that most Christians know is this: whoever believes and is baptized will be saved. This belief is not one that God merely exists, but that everything He says is true. He said that He is the one and only God. He said Jesus is the only way to the Father, the only means of forgiveness and rebirth.
Because we believe Him, we should desire to obey Him. Some people try to separate “faith” and “works.” It’s true that works without faith accomplish nothing eternal, but “faith” without good works is self-deception. If we truly believe, we will obey the commands of God. If we believe He truly loves us like He said, we will love Him. If we believe Jesus meant what He said when He said things like “turn the other cheek” and “go the extra mile,” that’s the way we will live. We will love one another, because we believe that following that command is righteous and good.
The commands of God can be seen this way: as promises of righteousness. Yes, at first they simply reveal sin, condemning our own evil ways, revealing our need for the Savior. However, once we’ve repented and turned to God, submitting our lives into His hands, the commands are revealed to be joyous promises of who we are now becoming. More than just rules to obey, they become a source of hope.
When we believe the promises of God, we have no other options. He said we are forgiven, and so we are. He said we have everything we need, and so we do. He also said, “You therefore must be perfect, as your heavenly Father is perfect.” Jesus wasn’t lying when he said that. He wasn’t exaggerating. We who believe will most certainly be perfectly good, for that is who He created us to be.
“Whoever receives his testimony sets his seal to this, that God is true.”–John 3:33
