Too Good to Be True?
Aren't we, in most circumstances, predictable? We quite prone to disbelief, and it seems not to make a big difference whether we have experienced a series of setbacks ("After what I have just been through, I can't believe this is happening to me! God, why are you doing this to me?") or it is good news ("No, HE can't be giving me a compliment" "I won the lottery? You must be joking!"). We just plain struggle with belief.
Peter was trying to give Jesus a means test: Lord, if it is you, bid me to come to you on the water. And Jesus said Come.
When Peter was concentrating on Jesus, had Jesus as his beacon and focus, he too could walk on water. Just as soon as he lost sight of his goal/purpose (getting to Jesus) and began noticing the wind and the waves, he started sinking. He cried to be saved and Jesus rescued him with the remark "O man of little faith, why did you doubt?"
When it comes to God that IS the question. With our small minds, with our finite perspective, with our self preoccupation we doubt. Investing in faith, developing a sturdy faith foundation, our view of life and God's promises and assurances become fortified. We learn to trust the Word of God. With our eyes of steadfastly fixed on Christ who gives us meaning and purpose and love beyond our understanding, we can put aside our disbelief. Yes, God is good AND true. Put your faith on it!
