'Sincerely' in the Bible

“Now then, if you acted in truth and integrity when you made Abimelech king, and if you have dealt well with Jerubbaal and his house, and have dealt with him as he deserved—

if then you have acted in truth and integrity with Jerubbaal and his house this day, then rejoice in Abimelech, and let him also rejoice in you.

When He killed [some of] them, then those remaining sought Him,And they returned [to Him] and searched diligently for God [for a time].

The Lord is near to all who call on Him,To all who call on Him in truth (without guile).

“Draw me away with you and let us run together!Let the king bring me into his chambers.”
