It's so odd how I can memorize some memory verses so easily and struggle to memorize others. I still mess up a verse from March 1.
My current verse is John 5:4
Remain in me, as I also remain in you. No branch can bear fruit by itself; it must remain in the vine. Neither can you bear fruit unless you remain in me.
I've seen in my life and ministry the lack of fruit at certain times because I had wondered away from God and could not even reach the vine much less discern God's will for me. I think it's a common problem for Christians upon occasion.
If you feel you cannot reach the Vine, remember Jesus has His arm extended to you and wants you to grab hold of His hand. If you are not sure how to find your way back, Revelation tells us: Yet I hold this against you: You have forsaken the love you had at first. Consider how far you have fallen! Repent and do the things you did at first.
Remember the joy you experienced when 1st saved? Return to the things you did back then. Get back into the Word, spend time in prayer and praise. Before you know it - you will know you are abiding in Him and you are a branch on the Vine.
