Once you are bitter, you are not looking better for yourself. We need to surrender your problems to Jesus and don't keep it for surely you will become bitter. We should not be afraid to talk to God when you're bitter.
2 Corinthians 5:19-20
19 that God was reconciling the world to himself in Christ, not counting people’s sins against them. And he has committed to us the message of reconciliation. 20 We are therefore Christ’s ambassadors, as though God were making his appeal through us. We implore you on Christ’s behalf: Be reconciled to God.
Job wanted to reconcile before God. Part of this book is The testing of Job's Life. Nature of men is we want to defend ourselves, but we should let God alone defend ourselves.
In 1 John, you can see in this book that Jesus is our attorney who will never be defeated.
1 John 2:1 My dear children, I write this to you so that you will not sin. But if anybody does sin, we have an advocate with the Father—Jesus Christ, the Righteous One.
In verse 1-7, Job come near to God. When we worship God we should not worship image or anything else but in spirit and in truth.
That's why we have trials, it is the reflection of what we are responding to it, a reflection of Christ Jesus.
Psalm 66:16 Come and hear, all you who fear God;
let me tell you what he has done for me.
James 1:4 Let perseverance finish its work so that you may be mature and complete, not lacking anything.
1 Peter 1:7
These have come so that the proven genuineness of your faith—of greater worth than gold, which perishes even though refined by fire—may result in praise, glory and honor when Jesus Christ is revealed.
John 8:12 When Jesus spoke again to the people, he said, “I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life.”
2 Timothy 3:16-17
16 All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, 17 so that the servant of God[a] may be thoroughly equipped for every good work.
2 Peter 2:20-22
20 If they have escaped the corruption of the world by knowing our Lord and Savior Jesus Christ and are again entangled in it and are overcome, they are worse off at the end than they were at the beginning. 21 It would have been better for them not to have known the way of righteousness, than to have known it and then to turn their backs on the sacred command that was passed on to them. 22 Of them the proverbs are true: “A dog returns to its vomit,”[a] and, “A sow that is washed returns to her wallowing in the mud.”
Every good and perfect gift is from above including bad things or trials.
Proverbs 19:29 Penalties are prepared for mockers,
and beatings for the backs of fools.
Romans 11:33 Oh, the depth of the riches of the wisdom and[a] knowledge of God!
How unsearchable his judgments,
and his paths beyond tracing out!
We should see the reality of God's faithfulness to us.
