The Lord Jesus Christ learned obedience by the things he suffered. The experience of afflictions and tribulations that we are passing through are trainings for us. They are God’s way of sharpening our lives. We might pass through some tough times in life, those experiences are there as part of God's plan for our lives.
James 1:12 (KJV) Blessed is the man that endureth temptation: for when he is tried, he shall receive the crown of life, which the Lord hath promised to them that love him.
The Bible says we should endure tribulations. That is what the Bible teaches us. We should endure afflictions knowing that the Bible has promised that we who endure afflictions will receive the crown of life. Trials and tribulations are for our training. They are not altogether bad. The good side of tribulations in life is that it trains us to face life with strength.
James 1:2 (KJV) My brethren, count it all joy when ye fall into divers temptations;
We should not complain when we pass through tribulations. The tribulations will not last forever. When we have learned what God wants us to learn from them, they will leave our lives.
