1 Thessalonians 5:18
Give thanks in all circumstances; for this is the will of God in Christ Jesus for you.

The good times and the bad times are included in this verse. The good times are easy but the bad times??? Well it is through those bad times that we need Him more than ever before! Our faith is a faith of DEPENDENCE, dependent on His love, goodness, and grace. You wanna do God's Will? It is simple, be Thankful in all circumstances.
