"Knowing that the testing of your faith produces patience. But let patience have its perfect work, that you may be perfect and complete, lacking nothing. If any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach, and it will be given to him. But let him ask in faith, with no doubting, for he who doubts is like a wave of the sea driven and tossed by the wind. For let not that man suppose that he will receive anything from the Lord; he is a double-minded man, unstable in all his ways." (James 1:3-8)
Our faith is being constantly tested, it doesn't matter who we are: assistants, members, pastor's wife's, etc. Friends, we are always being tested! In our home, job, school, church, during a meeting, during a conversation and in the deepest part of our being. Everyone is tested! The difference is that not everyone is accepted. Only those that have been accepted receive perseverance. It doesn't matter how hard things might become, whoever perseveres keeps their faith and their calling. There is no way for you to keep one and lose the other.
If you are one of the few who desire to do the Work of God, to serve Him, know this: You are desired both by God and the devil. God is waiting for you, and the devil is working against you.
