Our primary purpose is to love God. Our secondary purpose is to love our neighbour as ourselves.
Mark 12:29 And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord: 30 And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment. 31 And the second is like, namely this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these.
We love God when we obey his commandments.
Luke 9:35 And there came a voice out of the cloud, saying, This is my beloved Son: hear him.
Hebrews 1:1 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, 2 Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by (on account of) whom also he made the worlds;
If we love God, we will believe and obey the gospel taught by Jesus Christ and his apostles.
Mark 16:15 And he said unto them, Go ye into all the world, and preach the gospel to every creature. 16 He that believeth and is baptized shall be saved…
After repentance and baptism by immersion in water for the remission of past sins, we are to live a new life.
Romans 6:4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
Our new life must be lived in accordance with Christ’s commandments.
John 15:14 Ye are my friends, if ye do whatsoever I command you.
We must choose a job in the execution of which we are not required to break Christ’s commandments.
For example: Jesus was a carpenter; Peter a fisherman; Paul a tentmaker; Luke a physician; Lydia a seller of purple, and Tabitha a seamstress.
Clearly, we must not seek employment in the military, judiciary or munitions.
We are baptised into a body of believers. Our choice of job should allow us to meet regularly to remember Christ’s sacrifice by sharing bread and wine, to examine ourselves and to edify one another.
I hope you find this helpful.
