There is a purpose for the suffering. So that we won't be forever babes, but rather battle tested faith warriors
James 2:2 My brethren, count it all joy when you fall into various trials, 3 knowing that the testing of your faith produces patience. 4 But let patience have its perfect work, that you may be perfect and complete, lacking nothing.
There is also a limit to the trials
1Cor 10: 13 No temptation has overtaken you except such as is common to man; but God is faithful, who will not allow you to be tempted beyond what you are able, but with the temptation will also make the way of escape, that you may be able to bear it.
Most of our suffering is brought on by ourselves, our choices.
Would agree with this, as believers have trails, and various things that come in life; which produces a stronger faith - trust in God - trusting the Lord Jesus Christ. (Romans 5:1-10)
Say suffering from losing a parent, friend, brother. ~ Something that can be learned from; though the only comfort (2 Corinthians 1:3) found is that of God, and the Lord Jesus Christ ~ Thankfully.
Say suffering from choices made in life ~ Something that can be learned from: Thankfully, God is love (1 John 4:7-21), merciful (Deuteronomy 4:31), and forgiving (John 3:15-20) ~ Thank God the Lord Jesus Christ paid for the sins (1 Timothy 2:6) of the entirety of the human population once and for all (Hebrews 9:28) on the Cross, bringing forth the (Matthew 5:17-20) fulling of the law and the prophets which were promised to becoming since the beginning to be fulfilled. ~ That anyone who believes can have (Romans 5:1-2) peace (Philippians 4:6-7), being justified by faith in and through the Lord Jesus Christ.
The thing is we must accept in the aspect of as human beings we are all responsible for how our soul is acting ~ which Jesus Christ and God Helps by - renewing our mind, and our hearts (Ephesians 4:23; Ezekiel 36:26; Ezekiel 11:19; Jeremiah 31:33; Hebrews 8:10), and not being conformed to the world (Romans 12:2). Our soul - holds our Mind/Will/Emotion according to the Greeks.
Anyway just felt speaking a bit more, thank you for your post and time. Riverwalker.
