How strong is your faith? Look at the people described in Hebrews who had incredible faith. Look at what they achieved and/or sacrificed because of their faith. We are told that not all of them received their promise on Earth; is your faith strong enough to persevere even if you never never get what is promised while you are on Earth?
I know I do not have faith nearly as strong as Moses, Abraham, David, etc. I know that and I pray for increased faith each day. I pray for chances to find out how strong my faith is so I know where I stand. I know God will not tempt beyond the strength of my faith but I won't know how strong my faith is until it is tested.
How strong is your faith? None of us should rest comfortably thinking our faith is strong enough. Until Heaven returns with Jesus leading the charge, the Devil has opportunities to tempt us away from God.
The Devil will find weaknesses in our faith so we must never rest thinking we have enough faith, we must build it up each day to face the enemy and overcome.
Matthew 6 describes not worrying about tomorrow because today has enough troubles. Don't focus on tomorrow's problems until you get past today's problems.Pray that your faith in God will guide though each day and that it will grow stronger with each trial.
