But the one who received the seed that fell on good soil is the man who hears the word and understands it. He produces a crop, yielding a hundred, sixty or thirty times what was sown.” (Matt 13:23)
Understanding what Christ wants from us is easy. He wants our love, our dedication and our prayers. He wants us to plant seeds in others. He wants us to be obedient to his word. He wants us to have faith and to keep the faith we have! It is human nature to doubt, but then where would we be if we always doubted everyone or everything? The motives of others are not for us to worry about. Their judgement will come in his time as well as our own. We don't always go about things with the "proper motives", we justify what we do under the mistaken belief that it is for the "greater good".
Stop where you are and look at yourself. Are you everything that God wants you to be? Have you done something thinking you are "helping God" keep someone on the right path, when in reality you were just trying to control a situation that was none of your business? I know that I have. I hang my head in shame sometimes when I think of the things of tried to accomplish in HIS name.
The bright side is, he is a forgiving God. Let go of what it is that you feel you need to control or keep tabs on. Don't let the enemy convince you that it's your place to stick your nose in where it doesn't belong. The only place your nose belongs, in some situations, is pressed against the palms of your hands while you ask for forgiveness and mercy. God knows all things, he knows your heart and what you were trying to do (even if you weren't going about it the way he wants you to). Ask him to heal, or mend, or enlighten the person you are trying so desperately to keep (or get) on the right path. Ask him to open their heart to what it is they aren't seeing. Be strong, stand firm and lift up your voice to him ~ he hears your pleas and cries! He has promised us eternity - what more could you possibly want?
