When do we get bored ? when we got weary by monotony ( doing the same thing over and over again and getting tired and have lost our joy) or all of a sudden we seem to be at a loss of what to do.
Being a Christian, being bored could be dangerous moment to have because we might be tempted to do something that is not God glorifying, but being bored could be an opportunity to go to next level in our Christian walk.
Pray to God to let us know what is going on and ask Him what He wants us to do. Another one is to look at the fruit of the Holy Spirit in our lives. Galatians 5:22,23 But the fruit of the Spirit is love, joy, peace, patience, gentleness, goodness, faith, meekness, temperance against such there is no law. (Perhaps we are missing one or more ingredients).
Galatians 6:9,10 also says and let us not be weary in well doing: for in due season we shall reap , if we faint not.
As we have therefore opportunity,(according to St. Paul),let us do good unto all men, especially unto them who are of the household of faith.
