Unless hindered by circumstances out of one's control (such as illness or emergency), the Christian will ache in their heart whenever they miss church. Grace-driven motives makes church attendance not a matter of a check-off list item, but rather an event whereby I reinforce my love for Jesus by being around other Christians. Hebrews 10:25 states - "and let us consider how to stimulate one another to love and good deeds, 25 not forsaking our own assembling together, as is the habit of some, but encouraging one another; and all the more as you see the day drawing near."
Come back tomorrow, dear reader, as we will look at further assurances of salvation described by 1 John. May the Lord bless you this Lord's day.
