The Bible says in Luke 6:38- "Give, and it will be given to you: good measure, pressed down, shaken together, and running over will be put into your bosom. For with the same measure that you use, it will be measured back to you.”
I want to make some quick observations here-
1. This passage has nothing to do with money.
2. In the context Jesus is telling us to be merciful to others to forgive others and to simply walk in love.
3. When we do this, we will reap back from God a running over in our bosom of joy and peace and more of a fullness of God's presence in our lives.
Even though it is true that when we give money we reap back from God blessings, we must read scripture in its context. If we do give money we cannot give soley to receive money back from God. We give money because we love God and because we want Him to be glorified in our lives.
And for what it's worth, I want to guarantee you from personal experience, that this is the main goal of God in your life...TRUE love. Until we allow Him to teach us this truth, to walk in love, we will have a very difficult Christian walk.
Being a Christian is learning not just to follow Jesus physically, but following Jesus' heart. All we have to do is read the Gospels and pray that God will reveal to us who He really is and He will.
What brings God's blessing and favor into our lives is to walk in love and forgiveness and mercy to other people just as God has shown to us. One sure way to not please God is to treat others in a way we do not want to be treated. On the other hand, if we desire in our hearts to be like Jesus and to forgive and to be merciful and to walk in love, and we are asking God to help us do this, you can be sure He is pleased, even though you might fall short.
Don't give up when you are tempted to be too hard on others or if you fail. Get up confess your sins ask Jesus to save you from yourself, He is so faithful. I have seen it time and time again, God is faithful to mold us into the image of His Son Jesus Christ, our job is to trust Him and to love Him above all.
