If we have deep-seated fears that God does not really love us (as many Christians have), we can only go so far in growing nearer to God. There will come a point at which we will fear to trust Him any further because we cannot be sure of His love. When we look at ourselves, or our own faith, or our circumstances we will never be free from those lurking fears. Satan will see to that. But when we lift up our eyes and look on the cross we find the final persuasion that God is gracious towards us. How can He be against us when all His wrath against us fell upon Christ? How can He fail to care for us when He gave the only Son He had for our sake? How can we doubt Him when He has given us evidence of His love sufficient to banish all doubts?
