what is one's responsibility, as a believer?
There are so many correct answers to this question. Here is another. 🙂
To bring glory to God
Ephesians 2:8-10 NKJV
[8] For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, [9] not of works, lest anyone should boast. [10] For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.
1 Corinthians 15:56-58 NLT
[56] For sin is the sting that results in death, and the law gives sin its power. [57] But thank God! He gives us victory over sin and death through our Lord Jesus Christ. [58] So, my dear brothers and sisters, be strong and immovable. Always work enthusiastically for the Lord, for you know that nothing you do for the Lord is ever useless.
1 Peter 4:11 NKJV
[11] If anyone speaks, let him speak as the oracles of God. If anyone ministers, let him do it as with the ability which God supplies, that in all things God may be glorified through Jesus Christ, to whom belong the glory and the dominion forever and ever. Amen.
