The Lord is not slow in keeping His promise as some understand slowness, but is patient with you, not wanting anyone to perish but everyone to come to repentance.
KJV
The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
ASV
The Lord is not slack concerning his promise, as some count slackness; but is longsuffering to you-ward, not wishing that any should perish, but that all should come to repentance.
