God is sovereign; meaning that he is in control of everything and has a plan. When he does one thing, he is doing a million things. Whether he is doing miracles or whether he there is suffering God ultimately has a plan and is in control of the situation.
In Acts we see both miracles and suffering which are used by God for God. After the healing of Aeneas (Acts 9:32-35) it says “all the residents ...turned to the lord”, and after the healing of Dorca “ it became know throughout Joppa and many believed in the Lord” God is using these miracles not only to heal individually but also corporately.
After the stoning of Stephen(Acts 7:54-60) there was a persecution against the church in Jerusalem and the church scatters (Acts 8:1) God uses this persecution to spread the Gospel outside of Jerusalem.Likewise After Ananias and Sapphira’s death, great fear comes upon all who hear (Acts 5:5,11) which leads to the church being held in high esteem (Acts 5:13). Furthermore, Peter and Johns arrest leads to the strengthening of the church in Acts 4:24, 31
The reality is that we live in a fallen, broken world that is corrupted by sin and we should expect suffering. Fortunately we have a loving, sovereign God who works out all things for good (Rom 8:28) Though he has freed us from the penalty of sin, and is from the power of sin, we are not yet freed from the presence of sin but one day we will be.
When I read the book of Acts I see that there are in fact good times and bad times but I also have a loving God who is in fact with me(Acts 18:10) and in control. Those who call themselves Christians should expect suffering and can be content in every situation, because as Paul says in Philippians 4:13 “ I can do all things through Christ who gives me strength”
