True human interactions must be honest and genuine: “But as God is faithful, our word to you was not Yes and No. For the Son of God, Jesus Christ, who was preached among you by us—by me, Silvanus, and Timothy—was not Yes and No, but in Him was Yes” (2 Corinthians 1:18–19).
Unlike the second son in the parable, who said “yes” but did not follow through, our “yes” must be sincere—without hesitation or doubt—and must be a true application of God’s commandments.
If a person sins, God is always willing to accept his repentance: “The Lord is not slack concerning His promise, as some count slackness, but is longsuffering toward us, not willing that any should perish but that all should come to repentance” (2 Peter 3:9).
