The seven churches of Revelation faced the same problem as churches today- trials, persecution and false teaching. -Philadelphia is one of only two of these churches which the Lord does not criticise- instead, He promises to protect them from a coming trial.- 'Little strength' is sufficient - for them and also for us - because it is undergirded by His promises.--Main Headings---1- It's alright to have little strength-2- Conserving our strength-3- Pray for more strength
