Tribulation is now part of this life because of sin. Pains and hardship entered this world through sin, and sin is the author of all the pains we're passing through today. Everyone experience tribulation both the righteous and the unrighteous people. Tribulation is not always a sign that God has abandoned someone; sometimes it is simply the result of living in a world affected by sin and human choices.
When tribulation hits, it can make us stronger because it looks like test to our faith. Tough time is when many believers and non believers turns to God for help. Just as gold is refined by fire, faith can be purified through trials. God can use suffering to teach patience, humility, and dependence on Him rather than on human strength.
Sometimes tribulation is caused due to the righteous life we're living. Many people will reject you and persecute you because you're following God. Yet such suffering is not meaningless. It identifies believers with Christ and reminds them that their hope is not only in this life but in the eternal reward God has promised.
