We are to stay excited for the work of God. We are to always have a heart for the Lord and be ready with an answer for the unbeliever. My current study of 1 Peter reinforces this. In today's world, more than ever, we need to be planting seeds and being excited for Christ. Let the Holy Spirit do the hard part. We can not bring anyone to Jesus, that is His job. We can give information, answer questions, lead them to where they need to be. But the Holy Spirit introduces them to Jesus, Jesus invites them into His life and God saves them from the life they used to have. What an amazing friend we have. We need to make sure everyone sees Christ in us and wants what we have.
So get excited about God again if you have lost that "feeling". Know that He can help you every step of the way. Every time you bring someone to the Lord and they accept Jesus Christ, there is a celebration in Heaven and that is reason to be excited. Share in that victory!!
