God constantly refines both my character and my faith through difficult circumstances. He has done it most often for me by putting difficult people in my life and challenging me to love them. This forces me to lean on God for my ability to love, since the individuals are sometimes not what the world would consider 'lovable'. It forces me to turn to God for my sense of worth, because the individuals do not necessarily give me much positive reinforcement. It humbles me, because when I am impatient or angry or sin against them, the Spirit shows me that I have to confess it and ask their forgiveness. Then, at times, God gives me insights into how he is at work in their lives and mine, and I am so grateful for the trials and the struggles that keep my need for God at the forefront of my life.
Genuine tested faith brings glory to Jesus. Here it is in a nutshell:
2 Corinthians 4:5-10
5For we do not preach ourselves, but Jesus Christ as Lord, and ourselves as your servants for Jesus' sake. 6For God, who said, "Let light shine out of darkness,"[a]made his light shine in our hearts to give us the light of the knowledge of the glory of God in the face of Christ. 7But we have this treasure in jars of clay to show that this all-surpassing power is from God and not from us. 8We are hard pressed on every side, but not crushed; perplexed, but not in despair; 9persecuted, but not abandoned; struck down, but not destroyed. 10We always carry around in our body the death of Jesus, so that the life of Jesus may also be revealed in our body.
