Jesus was willing to die for us to save us, and He wants us to be willing to sacrifice and even die for His cause to save others. (1John 3:16) He bought and paid for us, we're His property, we belong to Him now. Jesus saved our souls, saved our lives for Eternity! So of course we should give our lives and try to win as many others as we can!
Jesus didn't go half-way to the cross for you, or almost all the way, but He went ALL the way, and gave all His life for you! The main job He came to do was to die on that cross, and so the main job you've got to do is bear your cross. He said, "If any man will come after Me, let him deny himself and take up his cross daily and follow Me. For whosoever will save his life shall lose it: but whosoever will lose his life for my sake, the same shall save it." (Lk.9:23,24) He is no fool who gives what he cannot keep to gain what he cannot lose.
We can only find the fullness of faith that we seek in the path of complete obedience, when we're really willing to take up our cross and deny ourselves, yielding our pride and our will to follow Jesus.--Then He will give us the power to follow as we surrender to Him!
