The human body is made up of many members, each having a specific job and function. For example, ears were made for hearing, tongue for talking and so forth. By looking deeper than the physical functions, we can see spiritual duties as well.
First Corinthians 16:13 and 2 Corinthians 1:24 both tell us that we stand by or in faith. Philippians 1:27 says, "…stand fast in one spirit, with one mind striving together for the faith of the gospel." We stand by faith striving for the Gospel by standing on a solid foundation. The only foundation solid enough to hold us is Christ. "For other foundation can no man lay than that is laid, which is Jesus Christ" (1 Corinthians 3:11). We stand on Christ through faith.
We find faith to stand by hearing God's Word (Romans 10:17). We must hear the Gospel and know the Gospel in order to strive for faith in the Gospel. "Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth" (2 Timothy 2:15). By hearing and studying the Gospel, we stand on Christ through faith.
"Therefore all things whatesoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets" (Matthew 7:12). By reading Matthew 25:31-46, we see that we must help others in order to enter into the kingdom of heaven. By hearing and studying the Gospel, we stand on Christ through faith by helping others.
Galatians 6:2 says, "Bear ye one another's burdens, and so fulfill the law of Christ." According to Romans 12:15, we are to "…weep with them that weep." While bearing the burdens of others and putting our burdens onto others, we must be careful not to take too much or give too much of those burdens. "For every man shall bear his own burden" (Galatians 6:5). We must all take the responsibility of our own burdens as well as share the burdens of others. This may seem to be a lot of weight on our shoulders, and rightfully so. That is why we also are able to cast our burdens on the Lord (Psalm 55:22). By hearing and studying the Gospel, we stand on Christ through faith by helping others and bearing their burdens.
While listening to God's Word and studying for ourselves, we are also commanded to teach his Word. Mathew 28:19 tells us to go and teach all the world. The early church teaches us by example in Acts 5:42 to teach and preach continuously. By hearing and studying the Gospel, we stand on Christ through faith by helping others and bearing their burdens while teaching them his Word.
We have many obligations, to ourselves and others. These obligations are all commandments of our Lord; so neglecting them would be, in fact, neglecting God. Not keeping his commandments would be transgression of God's law. "Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law" (1 John 3:4). Those that sin and keep not his commandments cannot enter the kingdom of heaven. "For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord" (Romans 6:23). Are you neglecting your obligations, or are you performing them?
