My friend, in this world there are going to be troubles, it is inevitable. But God is omniscient, and He knows every situation you will encounter, He even knows how you will respond in the mist of those circumstances. We must rely on His grace in our difficult times.
You know you are God’s child. But, like all of God’s children, you have sinned since you received Christ. You grew up in a church environment of well meaning Christians, but, they were unknowingly, legalists. My friend, be encouraged! We love you, so listen.
