"He presented another parable to them, saying, "The kingdom of heaven is like a mustard seed, which a man took and sowed in his field; and this is smaller than all other seeds, but when it is full grown, it is larger than the garden plants and becomes a tree, so that the birds of the air come and nest in its branches." (Matthew 13 :31-32)
Never despise small beginnings or little changes. Sometimes things in life can seem so daunting we don't think we will ever get there. Thankfully all things are possible through Christ, who strengthens us. This is a really powerful principle. Just start somewhere. Maybe you want to be more consistent in your Bible reading and you've been frustrated in maintaining a reading plan. Try something less demanding -- maybe start with a chapter or two per day. Then trust the Lord to help you. Better to read a little a day that sinks in and effects change than to blaze through large portions just to fulfill a reading plan. There's nothing wrong with reading plans, but the purpose is relationship and growth, not to mark off a check list.
This is a principle that we can apply to any area or struggle of life. Thankfully we have a wonderful heavenly Father who wants to help us. We tend to look at the big picture and get frustrated that we're not getting results fast enough, but the real question to ask is "Father, what can I do now?" He will show you the next step. Sometimes it is just to pray. Sometimes the only thing to do is rest and trust. The Holy Spirit always knows the most efficient path. Trust Him. Don't despise where you are today. Trust the Lord to walk you through.
