A key passage of Scripture that addresses the issue of attendance at called assemblies of the church is Hebrews 10:25. The passage states, "Not forsaking the assembling of ourselves together, as the manner of some is: but exhorting one another: and so much more, as ye see the day approaching". In spite of the very direct call of this passage for brethren to faithfully attend all assemblies of the church, we rarely see congregations with the same attendance at all gatherings. Mid week Bible Study assemblies usually have 40-75% of the Sunday morning worship attendance. Sunday evening worship assemblies usually number 50-80% of Sunday morning worship. There are some exceptions, but very few. Why does this occur? I believe brethren fail to understand the serious consequences of forsaking called assemblies.
First, verse 24 says, "And let us consider one another to provoke unto love and to good works". Brethren who attend faithfully are "provoked" unto love and good works. Some may believe themselves adequately provoked without meeting with their brethren. Maybe so, but attendance is also needed to provoke "one another". This also teaches that attendance results in encouragement and strengthening of one another. Those forsaking the assembly are selfishly neglecting to encourage their brothers and sisters. We are all needed at every assembly.
Verse 26 reads, "For if we sin willfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins". The Hebrew writer (verse 29) says one has "trodden underfoot the Son of God, and has counted the blood of the covenant, wherewith he was sanctified an unholy thing...". The next verses (30-31) warn us that God will judge His people and take vengeance on the unfaithful. Verse 31 states, "It is a fearful thing to fall into the hands of the living God." These verses are strong warnings that those who forsake the assembly are willfully sinning against God and their brethren and will be considered to have "walked on Jesus" in disrespect and disregard for the sacrifice He made for us.
To neglect assembly attendance is a sin resulting in one's fall from grace, condemnation, and eternal punishment (verses 27-28). This matter is very serious and must be better taught and understood.
