Contradiction with Proverbs 14:12
This verse suggests a way that seems right to a man, leading to death, contradicting Matthew 18:13's notion of rejoicing upon finding the lost.
Proverbs 14:12: There is a way which seemeth right unto a man, but the end thereof [are] the ways of death.
Contradiction with Luke 15:7
Although similar in theme, this verse emphasizes more joy over one sinner who repents, which subtly contradicts the implication in Matthew 18:13 of rejoicing over recovering what was lost, including the unrighteous.
Luke 15:7: I say unto you, that likewise joy shall be in heaven over one sinner that repenteth, more than over ninety and nine just persons, which need no repentance.
Contradiction with Matthew 10:34-36
Jesus speaks of bringing division, not peace, which contrasts the joy and unity signified by the recovery of the lost sheep in Matthew 18:13.
Matthew 10:34-36: Think not that I am come to send peace on earth: I came not to send peace, but a sword.
Contradiction with Matthew 7:13-14
Suggests that few find the narrow path to life, contradicting the idea of collective rejoicing over one recovered as mentioned in Matthew 18:13.
Matthew 7:13-14: Enter ye in at the strait gate: for wide [is] the gate, and broad [is] the way, that leadeth to destruction, and many there be which go in thereat: [strait: or, narrow]
Contradiction with Jeremiah 6:16
Encourages walking in the ancient paths leading to rest, which appears in contrast to the dynamic pursuit of the lost in Matthew 18:13.
Jeremiah 6:16: Thus saith the LORD, Stand ye in the ways, and see, and ask for the old paths, where [is] the good way, and walk therein, and ye shall find rest for your souls. But they said, We will not walk [therein].
Paradox #1
The contradiction or inconsistency could lie in valuing one over many. If one sheep is prioritized over the safety of the 99, some might see this as unfair or inconsistent with protecting the majority. Yet, others might argue it shows deep care for each individual, indicating no contradiction. It depends on perspective.
