"Some will say: “It is expensive to travel, and it would be better for us to save the money and give it for the advancement of the work where it is so much needed.” Do not reason in this way; God calls upon you to take your place among the rank and file of His people. Strengthen the meeting all you possibly can by being present with your families. Put forth extra exertion to attend the gathering of God's people. 6T 39.1"
"Three times thou shalt keep a feast unto me in the year."
Both passages encourage attendance at religious gatherings. Exodus 23:14 mandates feasts, while EGW encourages attending meetings. The connection is thematic, but not a strong direct principle.
"Brethren and sisters, it would be far better for you to let your business suffer than to neglect the opportunity of hearing the message God has for you. Make no excuse that will keep you from gaining every spiritual advantage possible. You need every ray of light. You need to become qualified to give a reason of the hope that is in you with meekness and fear. You cannot afford to lose one such privilege. 6T 39.2"
"But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear:"
EGW's phrase "give a reason of the hope that is in you with meekness and fear" is a direct allusion to 1 Peter 3:15.
"But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you."
Both passages prioritize spiritual matters over worldly concerns. Matthew 6:33 encourages seeking God's kingdom first, while EGW advises letting business suffer rather than missing spiritual opportunities.
