He said therefore, “What is the kingdom of God like? And to what shall I compare it? It is like a grain of mustard seed that a man took and sowed in his garden, and it grew and became a tree, and the birds of the air made nests in its branches.” -Luke 13:18-19
You might not see your witness being effective, but don’t get weary in well-doing. Continue. Plant the Word wherever you go. Don’t keep that seed to yourself. When the Word is sown, it produces big results.
